Product Introduction:

The real-time closed-loop echo simulator generates real-time echo signals received by the radar based on dynamically updated target/environment information and radar operating modes and parameters. It can be used for radar performance testing under dynamic conditions and closed-loop simulation testing of control systems.

Product specifications and characteristics:

• Scene size: ≥ 100Km×100Km

• Calculate the number of grid points: ≥ 4M points

• Grid spacing: ≤ 1m×1m

• Signal bandwidth: ≥ 200MHz

• RF frequency band: X、Ku、Ka

• Simulation parameter update rate: 1ms

• Real time simulation of echo signals from large scenes/multiple batches of targets

• High performance heterogeneous real-time computing technology

• Real time parameter updates and real-time switching of working modes

Case analysis:

• Real time SAR echo simulation of a certain type of scene matching guidance system

Used for comprehensive experiments of a scene matching guidance system to assess the dynamic performance of the entire system. A large number of repetitive tests were conducted on the ground using this simulator to calculate the performance indicators of the system, while helping to improve system stability and reliability.
