摘　　要：提出了一种动目标检测雷达数字信号处理机内建自测试方法。该方法介于系统级和板级之间，集系统调试、在线测试和离线测试于一体，设计简单，易于实现。论证了处理机各个关键模块的具体测试方法。针对其中的“数据存储重排”模块和“ Ｆ Ｆ Ｔ 与求模”模块，计算了故障覆盖率。A new method of built-in self-testing for the digital signal processor in an MTD radar is proposed. The method is between board-level testing and system-level testing, integrating system adjustment, on-line testing and off-line testing in one BIST system. The implementation of BIST is offered, and the fault-coverage-rate of “data rearrangement” module and “FFT and moduling” is calculated.
