Project Introduction

In response to the characteristics of projectile targets—high flight speeds, rapidly changing trajectories, significant acquisition challenges, and stringent accuracy requirements—Beijing Sosike has introduced a ballistic tracking radar system solution. This system integrates target search, autonomous acquisition, precision tracking, three-dimensional coordinate measurement, velocity estimation, trajectory output, and status monitoring, providing stable, reliable, and rapidly deployable radar detection capabilities for range testing, ballistic measurements, low‑altitude target tracking, and related applications.

I. Overview of the Plan

In ballistic testing, target‑flight‑trajectory measurement, and complex low‑altitude target‑detection scenarios, conventional optical observation methods are susceptible to factors such as weather conditions, illumination, background clutter, and target velocity, leading to challenges in target detection, continuous tracking, and measurement accuracy. Particularly when dealing with high‑speed, small, long‑range projectile targets, a single approach often struggles to simultaneously balance search coverage, acquisition efficiency, and measurement precision.

It can output critical parameters such as target range, azimuth, elevation, and radial velocity, while also providing multi-target tracking, clutter suppression, anti‑jamming design, attitude measurement, and self‑diagnostic functions—making it well suited for establishing a specialized, engineering‑grade ballistic detection and measurement system.

The low-altitude environment is complex, and ground clutter, sidelobe interference, and the external electromagnetic environment can all degrade radar detection performance; therefore, the system must possess robust suppression capabilities.

5.  On-site deployment should not be overly complex.

Many application scenarios demand that equipment be transportable, rapidly deployable, and quickly expandable, while also balancing weight, size, and power‑supply requirements.

VI. Operating Principle

Upon activation, the ballistic tracking radar system first performs self‑tests of each module, verifies inter‑module connectivity, and conducts key parameter measurements. Once the system status is confirmed to be normal, the radar enters operational mode. During operation, control commands are transmitted over the network to the processing module, which generates the beam‑scanning sequence in accordance with mission requirements. The frequency synthesizer module produces RF excitation signals at the corresponding frequency points; after pre‑amplification, these signals are routed to the subarrays of the antenna array. Combined with real‑time beam‑steering scheduling and antenna‑array attitude information, phase‑shift control is implemented, ultimately forming a transmit beam directed toward the specified azimuth.

During the reception phase, the target echo signal enters the array subarray via the receiving antenna element, where it undergoes low-noise amplification, filtering, phase shifting, amplitude modulation, and power splitting/combing before being routed to the down-conversion chain. There, it is converted into an intermediate-frequency (IF) signal, which is then digitized, sampled, and packetized to generate multiple baseband channels. I/Q Signal. Subsequently, the signal processing module performs pulse compression, MTD It performs processing such as target detection, followed by correlation, smoothing, and filtering in the data‑processing module, outputting tracklets, trajectories, and display information. The system also features fault monitoring and diagnostic capabilities, enabling it to simultaneously present abnormal conditions, fault messages, and maintenance prompts on the operator‑control terminal.
