摘要
分析了高重频脉冲多普勒(PD)雷达导引头遮挡现象的产生机理,及其对导引头系统产生的影响,并基于这些分析提出了一种有效的抗遮挡算法,通过PRF跳变使导引头系统全程工作在无遮挡区,从而消除遮挡的影响。理论分析与仿真证明了算法的有效性。
This paper analyzes the forming reason of HPRF PD seeker eclipse phenomenon, and its affection on PD radar seeker system. Based on the analysis, an effective anti-eclipse algorithm is proposed. Using this algorithm, PD radar seeker system can work in the clear area by the alterable PRF, so the affection of eclipse is removed. Validity of the algorithm is proved by theoretic analysis and simulation.
