摘要: 平面陣單脈沖測(cè)角具有方位、俯仰二維方向信息耦合的特點(diǎn),需要利用二維單脈沖信息聯(lián)合進(jìn)行角度估計(jì)。本文基于最大似然單脈沖測(cè)角算法,采用線性約束自適應(yīng)波束形成方法,將二維角度聯(lián)合估計(jì)簡(jiǎn)化為一維角度估計(jì),具有較好的可實(shí)現(xiàn)性。計(jì)算機(jī)仿真結(jié)果驗(yàn)證了該方法的有效性。

Abstract: The monopulse estimation for planar array has the property of angle coupling in element and azimuth. 2-dimension monopulse information should be used together to estimate target angle. A linearly constrained adaptive monopulse estimation algorithm for planar array is proposed in this paper, which simplifies the 2-D combined angle estimation algorithm to 1-D angle estimation algorithm. The efficiency of this algorithm is confirmed by computer simulation. -
