大功率扫描信号的失真度分析及对ESM侦收的影响

Distortion Analysis of The High Power Scanning Signal and Its Influence on The Reconnaissance and Reception of ESM

大功率雷达信号环境模拟器在模拟扫描雷达信号时,由于脉冲行波管放大器的非线性,使得模拟的扫描雷达信号与实际的扫描雷达信号存在一定的失真,影响侦察设备对扫描信号的正确判断。阐述了其对电子支援措施(ESM)侦收设备的影响,并提出可通过增加发射机输出功率和减小与ESM设备之间距离减小模拟雷达信号的失真度。

When the high power radar signal environment simulator simulates the scanning radar signal,the nonlinearity of pulse traveling wave tube amplifier will bring about definite distortion between the simulative scanning radar signal and the actual scanning radar signal,which will influence the reconnaissance equipments on judging the scanning signal accurately.This paper expatiates its influence on the reconnaissance and reception equipments of electronic support measure（ESM）,and brings forward the methods to increase the output power of transmitter and decrease the distance between the simulator and ESM reconnaissance equipments to reduce the distortion degree of simulative radar signal.
