摘要/Abstract

摘要： 箔条、角反射器等质心干扰诱使雷达导引头目标指示角偏离目标，导致导弹脱靶.为了解决这一问题，该文利用目标与干扰极化状态的差异性，通过目标、干扰极化相位描述子构造出斜投影算子，然后采用斜投影处理来抑制雷达导引头质心干扰.鉴于实际中目标、干扰极化状态难以准确估计，重点分析了目标、干扰极化相位描述子估计误差对斜投影输出目标、干扰信号的影响，推导得到了斜投影输出目标、干扰信号误差解析表达式；在此基础上，进一步推导得到了斜投影输出干信比、单脉冲比误差与目标、干扰极化相位描述子估计误差之间的关系式.理论分析与仿真结果表明，斜投影处理后的雷达导引头测角误差与目标极化相位描述子估计误差无关，与干扰极化相位描述子估计误差有关；干扰极化相位描述子估计误差在-10度到10度范围内时，斜投影仍具有一定的干扰抑制能力，有助于提高导引头的测角精度.

Abstract: Target indicated angle of radar seeker biases off the target when the centroid jamming such as chaff cloud or corner reflector presents,which makes the missile miss the target.To address this problem,oblique projection is employed to suppress the centroid jamming in this paper,where oblique projection operator is constructed by utilizing the polarization parameters of the target and the jamming.Since the polarization parameters of the target and the jamming are difficult to be estimated accurately in reality,influences of the estimation errors of the polarization parameters of the target and the jamming on the output target signal and jamming after oblique projection are mainly analyzed.Analytic expressions of output signal errors of the target and the jamming are presented.Based on this,the output interference-to-signal ratio and angle measurement error after oblique projection are further derived.Theoretical derivation and simulation results both demonstrate that angle measurement error of radar seeker after oblique projection is unrelated to the estimation error of the polarization parameters of the target,and is related to the estimation error of the polarization parameters for the jamming.Oblique projection can suppress the jamming to some extent and is good for enhancing the angle measurement accuracy of radar seeker if the estimation errors of the polarization parameters of the jamming are within the range of minus ten degree to ten degree.
