square detector

ABA processor is a noncoherent monopulse processor operating at the output of square low detector. The performance of an ABA proc(?) sor is insensitive to phase imbalances at the IF stage of a monopulse receiver.

ABA处理器是工作在平方律检波器输出的非相参单脉冲处理器，其性能不受单脉冲接收机中频级相位不稳定的影响。

By extending matched filters and equivalent square bandwidth theory to photoelectric imaging system in which the optical system and detector are looked as linear systems.

将光电成像系统中的光学系统和探测器视为线性系统，应用匹配滤波和等效平方带宽理论，综合考虑了系统的信噪比和带宽，建立了基于信噪比通道宽度的系统性能评价模型。
