在雷达电子对抗中,假目标是回答式干扰机的干扰样式之一。它所起的作用,已经引起了人们的重视。为了各自的目的,雷达研制方,需要有模拟各种目标的信号产生器,而干扰机研制方也需要有模拟多目标的信号,作为回答式干扰机的一种干扰样式。总之,二者均需有模拟多目标的信号产生器。由于使用的目的和场合不同,多目标信号产生器的原理和组成等方面也略有不同。为了讨论方便,将雷达研制方需要的,称为雷达多目标信号产生器;干扰机研制方需要的,称为多目标干扰信号产生器。本文主要介绍这两种多目标信号产生器的工作原理及其组成。
In radar electronic warfare, the fake target is one of the interference patterns of answering jammers. The role it plays has drawn people’s attention. For their own purposes, radar developers need signal generators that simulate various targets, and jammer developers also need analog multi-target signals as an interference pattern for answering jammers. In short, both need to simulate a multi-target signal generator. Due to different purposes and occasions, the principle and composition of multi-target signal generator are also slightly different. In order to facilitate the discussion, the radar developers need, called the radar multi-target signal generator; interference machine development needs, called multi-target interference signal generator. This article describes the principle and composition of these two multi-target signal generator.
