MIMO雷达射频隐身性能的评估

Evaluation of RF Stealth Performance of MIMO Radar

电子干扰、反辐射导弹的现实威胁使射频隐身性能成军用雷达关键的指标之一,评估雷达的隐身能力因此也越来越重要。针对MIMO新体制雷达的射频隐身性能评估问题展开研究,详细描述了敌方电子侦察设备截获雷达信号的过程,分析时域、空域、频域对准和功率影响截获概率的若干重要因素,结合传统意义上的抗截获性能评估方法,提出了一种计算MIMO雷达截获概率的模型。仿真分析和对比了各个因素对截获概率的影响,验证了这一模型的实用性和有效性。

The threats from electromagnetic interference and anti-radiation missile make RF stealth performance be a key indicator of military radar, thus the evaluation of the radar viability becomes more and more important. Aiming at evaluating the RF stealth performance of MIMO radar, the interception process of radar signals by the enemy is illustrated in this paper. The key factors that affect probability of intercept are analyzed. Based on traditional evaluation methods, a model for calculating the probability of intercept of MIMO radar is proposed. Simulation results show the effectiveness and practicability of the model.
