Project Introduction

As the use of unmanned aerial vehicles and other low-altitude flying objects becomes increasingly widespread, low‑altitude safety risks are shifting from being “occasional” to “routine.”
Traditional security systems struggle to effectively address airspace targets that are low‑altitude, slow‑moving, small, stealthy, and sudden.
Leveraging composite sensing and intelligent interlocking technologies, SETTALL establishes a closed-loop low‑altitude defense system that encompasses search and early warning, target confirmation, continuous tracking, situational awareness, and decision‑support capabilities, thereby providing more proactive, smarter, and more reliable low‑altitude security for critical areas.

I. Overview of the Plan

The SETTALL low-altitude defense system is an integrated protection platform designed for deployment in critical low-altitude areas.
It is primarily designed to address low‑altitude, slow‑moving, small aerial targets such as drones, providing all‑day, all‑weather capabilities for detection, identification, target acquisition, tracking, positioning, display, reporting, and assisted response.

The system consists of Detection subsystem, display and control subsystem, and response subsystem Composition.
Through the collaborative operation of multi-source sensing devices, integrated analysis powered by intelligent algorithms, platform-based unified management, and GIS‑based situational awareness visualization,
Help users evolve from “identifying anomalous targets” to “establishing a closed-loop low-altitude security system.”

II. Industry Pain Points

Low-altitude security is facing new challenges.

Pain Point 1

Low-altitude targets are difficult to detect.

Unmanned aerial vehicles and similar targets typically exhibit characteristics such as low flight altitude, small size, slow speed, weak infrared signatures, and high unpredictability, making them difficult for conventional surveillance systems to detect in a timely manner.

Pain Point 2

A single device is unlikely to provide effective protection.

Single‑sensor systems—whether optical or radar—are prone to missed detections, false alarms, and tracking instability in complex environments characterized by clutter, building occlusions, terrain undulation, and climate variability.

Pain Point 3

After discovery, it is difficult to confirm and hard to coordinate.

Many systems can only “detect anomalies” but cannot quickly identify targets, continuously track them, or effectively integrate with command centers and response equipment.

Pain Point 4

Lack of unified situational awareness and unified management

In scenarios involving multiple types of equipment, diverse target categories, and geographically dispersed deployments, the lack of a unified platform often leads to information silos, delayed response times, and reduced command-and-control efficiency.

 

III. System Architecture

A systematic architecture integrating composite sensing, intelligent interconnection, and command-and-display control.

Architecture Description

The SETTALL low-altitude defense system adopts an overall architecture of “front-end sensing + central display and control + coordinated response.”
By coordinating multiple detection systems, an integrated capability framework is established, encompassing search and early warning, target confirmation, automatic tracking, trajectory display, situational awareness visualization, and coordinated response.

1) Detection Subsystem

Responsible for the search, detection, identification, warning, targeting, and tracking of low‑altitude targets.
It can integrate optoelectronic search sensors, tracking mounts, radars, and other front-end detection assets to meet airspace surveillance requirements across diverse operational scenarios.

2) Display and Control Subsystem

It is responsible for receiving target data, fusing multi-source information, visualizing 2D/3D GIS situational awareness, managing device status, recording alarm information, and providing visual support for command and dispatch.

3) Disposal Subsystem

It is responsible for implementing jamming and suppression or other coordinated actions against targets, in accordance with target priority levels and command strategies, thereby enhancing the closed-loop response capability for low-altitude security protection.

 

IV. System Workflow

From detection to response, a complete closed-loop low-altitude defense system is established.

Step 1: Airspace Search

Front-end optoelectronic, radar, and other sensors continuously conduct all‑day, all‑weather surveillance of the target area, providing real-time monitoring of suspicious low‑altitude flight targets.

Step 2: Target Alert

Upon detecting a suspected target, the system automatically triggers an alert and outputs key information such as the target’s bearing, range, speed, and trajectory.

Step 3: Linkage Confirmation

The system automatically guides the tracking device to the target area, enabling visual confirmation and detailed verification of the target.

Step Four: Automatic Tracking

Once the target is confirmed, the system automatically locks onto it, maintains continuous tracking, adjusts the focal length, and generates a trajectory profile, ensuring that the target remains within the surveillance link.

Step 5: Situation Display

Target information is synchronized and overlaid onto the GIS situational map, providing an intuitive display of target trajectories, equipment status, and regional situational awareness.

Step Six: Auxiliary Handling

The command and control center assesses the threat level of targets and coordinates with response systems to execute jamming, suppression, or other protective measures.

 

V. Core Competencies

Multi-source fused perception enhances the efficiency of low-altitude target detection and response.

Capability One

Composite detection capability

The system integrates the advantages of electro-optical and radar detection, balancing broad‑area search capabilities with fine‑grained identification, thereby enhancing the detection rate of low‑altitude targets in complex environments.

Ability Two

Intelligent Interconnection Capability

After the front-end search device detects a target, it can swiftly transmit information such as the target’s bearing, range, and latitude–longitude coordinates to the linked device, enabling automatic switching, automatic confirmation, and automatic tracking.

Capability Three

AI recognition capability

By integrating object detection with intelligent analysis algorithms, suspicious targets are identified and classified, thereby reducing false alarms caused by birds, complex backgrounds, and environmental disturbances.

Capability Four

Automatic correction capability

During continuous tracking, the system can dynamically compare the current tracking results with the search results; upon detecting any deviations, it automatically reacquires and corrects the target, thereby enhancing tracking stability.

Capability Five

All-weather operational capability

The system supports continuous day-and-night operation and is adaptable to complex climatic conditions, low-light environments, occlusions, and multi‑background interference, ensuring long-term surveillance of critical areas.

Ability Six

Situational awareness capability

The system supports 2D/3D GIS map visualization and can overlay key data such as target trajectories, device locations, perimeter‑zone information, and flight status, thereby facilitating unified command and decision‑making.
