| The error analyse of the radar muti-target simulator is about difference between the radar echo generated by the radar muti-target simulator and the corresponding one generated by the real target. The paper analyze the various errors of the radar muti-target simulator, and mainly discusses the quantization error caused by the echo time delay quantization of the radar muti-target simulator, the operation error generated by DSP when it stimulates the target echo and the extent and phase error of the I/Q double channels .Firstly, we introduce the basic information of the error analyse and the target movement equation of the muti-target simulator. And the structure and the principle of the system are also discussed. Then we discuss in detail the error of the stimulator and the source of it. The error model is established for the research of the effect caused by the error to the the radar echo generated by the radar muti-target simulator. Finally, the target echo pulse is emulated and the result is compared with what is simulated by the radar muti-target simulator so as to test the effectiveness of the radar muti-target simulator. |
