摘要
单脉冲技术已被广泛应用到各种精密跟踪系统中,但在干扰环境中,特别是干扰出现在主波束区域时会导致传统的单脉冲角度估计失效。在分析空时自适应单脉冲技术的基础上,提出一种基于对角加载的子阵级空间快时自适应最小方差单脉冲角度估计技术。在尽量不消耗过多系统自由度的前提下,该方法能够有效提高干扰情况下的单脉冲角度估计性能。
Monopulse technique is widely used in high accuracy tracking systems. However, in case of jamming, especially mainbeam jamming, conventional monopulse radar usually fails to estimate the Direction of Arrival（DOA）. After analyzing STAP monopulse technology, a subarray level SFTAP-MV monopulse technique based on diagonal loading is proposed and it proves that the performance of DOA under jamming without consuming much system degrees of freedom can be obtained.
