摘要

本文研究了机载相控阵雷达波束-多普勒域部分自适应处理系统的几种降维处理方法

主要包括辅助通道法(ACR)、局域联合处理方法(JDL)和空时相邻多波束法(STMB)

并从改善因子性能、自适应权、空时二维频响方面

讨论了几种可能有效的波束位置选择方案的合理性.理论分析与计算机仿真表明

空时相邻多波束法具有较低的系统自由度、优良的性能和很强的误差鲁棒性

是机载雷达非均匀杂波环境下一种可取的波束选取方案.

Abstract

This paper studies several reduced rank partially space-time adaptive processing(STAP) approaches in beam-Doppler domain for airborne phased array radar

which includes the Auxiliary Channel Receiver(ACR)

the Joint Domain Localized(JDL) approach and the Space-Time Multiple-Beam(STMB) approach.A comparative analysis is performed.Several selections of beam number and position are also investigated in detail based on improvement factor

adaptive weights and space-time two-dimensional response characteristics.Theoretical analysis and computer simulation further illustrate that the STMB approach has very low system degrees of freedom(DOFs) and good performance.It is robust to array element error and nonhomogeneous clutter

and therefore feasible and available for airborne phased array radar applications in nonhomogeneous clutter environments.
