Abstract :
The paper studies the design to implement moving target indication (MTI) and moving target detection (MTD) based on a piece of ADSP-TS203. Digital signal processor (DSP) provides great flexibility for the design of the software. After pulse compression, the radar echoes including clutter, noise and targets are transmitted to DSP for MTI and MTD. The system mainly adopts the arithmetic of three-pulse elimination to realize MTI. MTD can be completed by using a narrow-band-Doppler-filter group in frequency domain. At last, it´s verified that this system can restrain clutter and distinguish the targets effectively, which has been tested on the hardware. Meanwhile, the improvement factor is also improved. The system can be widely used in radar signal processing.
