A Study on Test Technology of Power-aperture Product of Active Phased Array Radar

有源相控阵雷达的发射具有分布式的特性，其发射系统功率孔径积的直接测量一直是工程中的难题。首先，介绍了一种雷达功率孔径积的测试原理、测试方法；其次，根据工程实际提出了直接法和比较法两种测试方法，并对两种方法的测试结果进行了比对；然后，给出了测试时波束法线对齐的逼近法流程、测试误差分析等；最后，通过对某型相控阵雷达的实际工程应用，进一步验证了测试方法的有效性。

Because of the distributed transmitting features, it is difficult to test the radiation power-aperture of active phased array ra- dar directly. Firstly, a new test principle and method of power-aperture product is provided. Secondly, according to the engineering reality, the direct test method and comparison test method are both provided, and the test results are compared. Thirdly, the align- ment algorithm of the normal direction of wave-beam and the analysis of testing error are provided. Finally, the correctness and valid- ity of the algorithm is indicated by the engineering application of testing power-aperture product of one active phased array radar.
