摘要/Abstract

摘要：

随着现代战场中电子对抗的日益激烈，雷达的生存环境受到了严重的威胁。射频（RF）隐身技术是一种提高雷达及其运载平台战场生存能力的重要途径。为提高雷达射频隐身性能，针对具有MIMO探测模式的新体制雷达提出了隐身性能优化的目标跟踪算法。该算法基于射频隐身性能优化模型，通过自适应控制系统的子阵划分个数、平均发射功率、波束驻留时间以及采样周期，在满足系统跟踪性能要求的前提下优化系统射频隐身性能，其中的射频隐身性能综合考虑了截获因子及采样周期。仿真结果表明，与传统相控阵雷达相比，本文所提出的目标跟踪算法使MIMO雷达具有更好的射频隐身性能。

关键词: 射频隐身, MIMO雷达, 目标跟踪, 截获因子, 采样周期

Abstract:

With the increasingly fierce struggle of electronic countermeasure in the modern battlefield, the environment of radar falls under serious threat. Radio frequency (RF) stealth technology is an important way to improve the viabilities of radar and its platform in the war field. In order to improve the radio frequency stealth performance of radar, a target tracking algorithm with stealth performance optimization is proposed for a new style radar system with MIMO detection mode. Based on the optimization model of RF stealth performance, the subarray division number, average transmission power, beam dwell time and sampling period are controlled adaptively in the tracking algorithm to optimize the RF performance of the system on the guarantee of tracking precision. Specifically, the intercept factor and sampling period are considered synthetically in the RF stealth. Simulation results demonstrate that, with the proposed target tracking algorithm, a MIMO radar can provide better RF performance compared with traditional phased array radar.

Key words: radio frequency stealth, MIMO radar, target tracking, intercept factor, sampling period
