发射波束部分阵元置零综合分析

Analysis of partial nulling for transmit beam forming

针对选择阵列部分单元控制的情况,分析了发射波束零点形成的两种方式,即部分阵元的幅相加权综合和部分阵元的唯相位综合加权方式。通过对这两种置零综合的算法研究和仿真分析,并从形成零陷的深度及对副瓣扰动等方面,比较了这两种发射波束置零综合方法的性能。

Partial array selects a subset of all the elements in an array to have weights. For this,two syntheses,partial amplitude and phase weighting and phase-only weighting are used to form nulling in array pattern. The algorithm performances are analyzed from two aspects of nulling depth and sidelobe disturbances based on computer simulation.
