摘　　要：论述了一种新的机载相控阵雷达视频信号模拟器中目标信号的模拟方法和基于TMS32 0C6 2 0 1的硬件实现。该模拟器采用软硬件相结合的方法 ,由计算机根据雷达工作参数预先设定并计算目标、杂波数据 ,然后将数据加载到硬件电路中 。In this paper, an implementation method of target signal in a new airborne phased array radar video signal simulator is discussed. The simulator was implemented by mixed means of software and hardware. Based on the radar working parameters and the user-defined radar echo environment, the proposed target and clutter data was calculated in advance by a personal computer. After the data was uploaded to SDRAM of the simulator by the computer via PCI interface, the real time calculating was carried out by TI TMS320C6201 DSP. The signal generation circuits compose the real time digital signal. The real time radar video signal was achieved by the digital signal after D/A converters.
