Pulse Doppler Radar Target Echo Simulation Study

The doppler radar simulator is used to analyze and validate the problem of one radar velocity measurement system. The simulator can mainly simulate the doppler frequency and range. Firstly, we come up with the principle of the radar x the problem and principle of velocity measurement with low-PRP radar. Then the composing and operation principles, we discuss the modeling and simulation technology of the three targets simulated, The echoes coherence methods is also referred. There're two methods of computing the doppler frequence , we compare them and get the better. The siginal processing system is hard-core of the simulator, we give it's scheme graph. The operation principles of the composing parts are discussed, including data acquisition, D/A, DSP, data memory, range time lag and doppler modulation. We also give the system frame diagram. At last, the thesis analyze the feasibility of the system, and simulate the data acquired by high-speed acquisition system.
