Multi-target track simulation based on DSP

A DSP based multi-target track simulation system, which can send the flying parameters to radar, is presented. The system simulated the tracks of multi-targets by special model and position information of the plane obtained from GPS receiver. The flying parameters including position, velocity and Doppler frequency were calculated. DSP chip and optimized algorithms were used to realize the real-time signal processing. Tests show that target position error is less than 1 m, velocity error is less than 2 m/s and the time of computation is less than 50 μs. The proposed system realizes the requirement of accuracy and real-time.
