摘要
旁瓣对消是现代雷达抗有源积极干扰的最有效的方法之一。文中介绍了一种早期闭环模拟旁瓣对消技术和现代闭环数-模结合旁瓣对消技术的原理。通过对早期闭环模拟旁瓣对消技术和现代闭环数-模结合旁瓣对消技术的探究,最终在工程上实现一种适合放置在接收机前端的易实现的旁瓣对消技术,使该系统在抗有源积极干扰中发挥更好的作用。
Sidelobe cancelling is an effective measure against active jamming. The principle of closed loop sidelobe canceling technology including traditional analog method and modem method using analog and digital knowledge is introduced in this paper. Based on the study of those, a sidelobe cancelling scheme is realized easily in project, which fits frontal receiver. This system using the scheme has better performance of ECCM.
