A general multi-channel radar echo simulator

A general-purpose multi-channel radar echo simulator is researched and proposed in this paper to satisfy the various needs of the radar signal processor testing. The specificity of target echo model is the main problem to achieve the generalization for a simulator. The simulator will give priority to the issue of the generalization because the generalization is always the most attractive feature for any device. Therefore, it will lose some other performance. For example, the accuracy of the target distance will be reduced since we consider the target will not move in a coherent integration frame to reduce the computation and complexity of the echo modeling. At last, implementation of a specific simulator based on FPGA and DSP is introduced, including hardware design and software processing methods.
