摘要
天线主波束指向代表了雷达的能量集中方向,其在电子对抗领域是一个十分重要的信息。当已知雷达天线的主波束指向时,可以避开目标雷达的探测或对其实施精准的电子干扰。基于雷达周围部署的少量观测点,构建噪声环境下的稀疏空间采样数学模型,并提出四种雷达阵列天线主波束指向的估计算法。蒙特卡洛仿真测试结果展示了所提算法在不同条件下的估计准确性。
The main beam direction of antenna represents the direction of radar energy concentration,which is a very important information in the field of electronic countermeasures.When the main beam direction of the radar antenna is known,the detection of the target radar or implement accurate electronic jamming on it can be avoided.Based on a small number of observation points deployed around the radar,a sparse spatial sampling mathematical model under noise environment is constructed.Four estimation algorithms for main beam direction of radar array antenna are proposed.The Monte Carlo simulation test results show the estimation accuracy of the proposed algorithm under different conditions.
