摘要
提出一种雷达接收机中高、中、零频(视频)噪声数据形成的有效方法.该方法在产生满足概率分布随机数的同时不断地用相关函数检验和筛选,使噪声数据序列不仅满足概率特性,也最终满足相关特性从而回避了直接在中频筛选噪声相关函数的复杂性.仿真结果验证了方法的有效性.
The author puts forward an effective approach to the formation of high, intermediate, and zero frequencies （including video frequency） noise data occurred in a radar receiver. The approach can check and filter the noise datum sequence continuously with correlation functions when generating the random numbers that meet the distribution of probability, which makes the noise datum sequence satisfy not only the characteristics of probability, but also that of correlation, avoiding the complexity caused by IF filtering noise correlation functions. Simulation results prove the availability of the approach.
