摘要
在介绍瞬时中频测试技术的基础上,介绍利用瞬时中频测试技术对捷变频雷达本振跟踪精度进行测试的原理和方法。重点介绍为提高测量精度而采用内插扩展技术和为克服噪声电平过高而引起测量电路误触发而采用的外闸门技术。
Bases on the IIFM technique, the principle and method to measure the local oscillator tracking accuracy of frequency- agile radar is put forward in this paper. Put emphasis on technique for improving the measuring precision and external gate technique for preventing measuring errors.
