摘　　要：在密集信号电磁环境的侦收显示屏幕上,单用视觉扫描观察被侦收的雷达信号参数,极易丢失所需的观测信号,特别是在人员少、需观察内容多的情况下更是如此。若利用听觉特点所具有的识别感知能力,就能充分发挥人体器官能动性。通过对被侦收的雷达信号的基本特征及处理系统识别被侦收雷达信号的过程的分析,提出利用听觉来引导视觉识别扫描信号参数的一种有用的辅助手段。介绍显示可听范围的脉冲重复频率、测定高速运动载体雷达信号多卜勒频率的方法、及转换为虚拟声音后指示方位、距离远近的基本途径。On the accepting display screen of intensive signal electromagnetism environment, it is easy to lose observation signal by using radar signal parameter accepted by vision observation,especially in the situation of few people and lot of contents. If making use of the identification sense of hearing characteristics and feeling consciousness dint,it can develop dynamic role of the human body organ. This paper describes the fundamental character of detected radar signal and a way of how processing system discerns this detected signal. It provides a necessary and useful auxiliary method of using sense of hearing to guide visual sense to discern the parameter of scanned signal. It not only introduces a method of displaying the repeated frequency of audible pulse and measuring the DS of high speeding carrier＇s radar signal, but also gives a basic way of indication position and distance with fictitious sound changed from this radar signal.
