Abstract
A radar system uses multiple nulls to improve detection capabilities. Multiple radar pulses are transmitted and or received, each with a different null pattern. The returns from each pulse are averaged together to form a null window that is less noisy and potentially wider than a single null pattern. This approach can improve the signal-to-noise ratio and make it easier to detect objects of interest. The system may generate individual pulses from an AESA divided into several subarrays. Each subarray produces a pulse with a null in a different location in the radiation pattern centered about a location of interest. The contemporaneous return signals are averaged together.
