In real-time radar simulation system

a module of Moving Target Detection(MTD) was realized by FPGA

which followed FFT doppler filter method.According to system generality requirements

the standard module interface was defined

and the range gate matix storage format was given.Using pipeline technology

1-RAM centralized structure was designed for saving resources.Then 2-RAM rotation structure was improved for more relaxed timing.Finally

group-sliding MTD circuit was proposed

and the refresh rate for target distance and velocity information increased many times.The results show that

all projects complete expected function

and the process delay reaches microsecond level.
