摘　　要：随着雷达技术的飞速发展,数字T/R组件逐渐取代模拟T/R组件广泛运用于各种相控阵雷达中。由于数字T/R组件功能强大,电路复杂,需要测试的参数比模拟T/R组件多,测试方法也发生了根本性的改变。文中介绍了数字T/R组件测试系统的组成和工作原理,提出了数字T/R组件核心参数的测试方法,并针对工程中遇到的实际问题提供了解决方案,实际应用表明这些方法的测试效率和分析精度可以满足数字T/R组件测试要求。With the quick development of the radar technology, the analog T/R module has been superseded by the digital T/R module in array radar. The function of the digital T/R module is more powerful, and the circuit is more complex, so its test method and platform construct are very different from the analog T/R module, with more T/R modules to be tested. This paper discussed the function and components of the digital T/R module test system. The principle of digital T/R module parameter testing method was introduced, and solutions for practical engineering problems were provided. The test results showed the efficiency and precision of these methods settle for digital T/R module testing.
