根据ＭＴＤ 雷达数字信号处理机的特点，分别讨论了信号域测试与数据域测试的内建自测试（ＢＩＳＴ）方法，提出了一种新的数据域ＢＩＳＴ方法，并计算了这种测试方法的故障覆盖率．该方法已成功地应用于某ＭＴＤ雷达数字信号处理机．
According to the characteristics of MTD radar digital signal processor, the built-in self-test (BIST) method of signal domain test and data domain test are respectively discussed. A new data domain BIST method is proposed and the failure of this test method is calculated Coverage. The method has been successfully applied to a MTD radar digital signal processor.
