摘要
星载侦察在现代战争中的作用日益显著,对相关技术的研究也成为热点。由于受到有效载荷的限制,星载接收阵列一般采取稀疏阵,因此分析稀疏阵对地面辐射源的测向性能具有重要的现实意义。分析了典型结构稀布阵对地面辐射源的测向性能及测向的实时性问题,所得结果表明5元稀布L阵能够实现对地面辐射源的实时高精度测向。
Satellite recognition is gradually important in modern wars, and relative techniques have become the study hotspot. Due to the limitation of virtual load, the space-borne arrays are commonly chosen to be sparse ones. so, analysis of the direction-finding ability to the ground emitters is particularly important. Estimation to ground emitters of space-borne sparse L-array is provided, and the simulation resuits obtained prove that such arrays are good at high accuracy direction-finding.
