单脉冲雷达天线差斜率测试技术的改进

内容简介：针对工程应用中单脉冲雷达差斜率简便测试问题，提出了一种正弦波单脉冲差斜率测试方法。推导了将非相参的正弦波信号用于差斜率测试的公式，并将正弦波信号直接用于单脉冲给差斜率测试系统，实现对单脉冲雷达系统参数的快速校正。仿真结果表明，经过该方法校正的单脉冲雷达系统可实现优于0.01°的测角精度。该测试方法能够实现高精度的系统测试性能，对解决工程应用中的测试校正问题具有实际指导意义。

Abstract：In view of the expediently testing problem for the slope of difference pattern for monopulse radar system in practical project, a testing method for the monopulse slope of difference pattern based on the sine wave is presented. Formulas are derived based on the non-coherent sine wave, meanwhile the testing sys-tem for monopulse radar based on the non-coherent sine wave is introduced and the testing method can rapidly calibrate the parameter errors of monopulse radar system. Computer simulation proves that the cor-rected radar system can obtain the angle measurement accuracy higher than 0 . 01 °. The method achieves higher accuracy of the testing system and it is instructive for solving test and calibration problems in mono-pulse radar in practical project.
