摘　　要：提出基于阵列的非合作无源探测体制。在该体制下利用阵列波束合成及多谱勒匹配滤波检测目标,采用远距离子阵作为长基线干涉仪实现高精度模糊测向,利用波束宽度约束并采用多约束下自适应波束形成技术实现解模糊,从而达到无模糊精确测向目的。理论与仿真结果表明,该方法是有效的。The system of non-cooperative passive location based on array is proposed.In the system,target is detected by beamforming and Doppler matched filtering;and bearing is measured by a long-base-line interferometer which is composed of long distance sub-arrays.For the interferometer has long-base-line,the bearing is measured accurately but ambiguously.To realize unambiguous accurately bearing measurement,beam width and multiple constraint adoptive beamforming technique is used to resolve azimuth ambiguous.Theor...
