在大多数相控阵雷达中，由和、Δ α和Δ β通道组成的三通道单脉冲系统用于角跟踪被检测目标。增加第四个单脉冲通道可以提供主波束干扰机的调零，以显著提高在干扰机波束宽度内的目标的可探测性。除了提高可探测性外，还可以利用这种技术在主波束干扰的情况下对目标进行角度跟踪。
A three-channel monopulse system consisting of the sum, delta alpha, and delta beta channels is used to angle-track detected targets in most phased array radar. The addition of a fourth monopulse channel can provide nulling of main beam jammers to significantly improve the detectability of targets that are within a beamwidth of the jammer. In addition to improved detectability, it is also possible to track targets in angle in the presence of main beam jamming using this technique.
