A Beam Domain DOA Estimation Algorithm Applied in Swarm UAVs Super-Resolution
In order to improve the resolution ability of swarm UAVs,a beam domain iterative adaptive approach(IAA)algorithm is proposed.This method not only avoids the high computational complexity and the need to select hyper-parameters of the traditional sparse representation angle measurement method,but also has a good resolving ability in non-ideal conditions such as single snapshot number and small spatial angle interval of target signal,which is compati-ble with the process of phased array radar beamforming and range-Doppler domain processing.Through simulation ex-periments,it can be shown that this method can help radar to distinguish dense targets in advance,and then accurately estimate the size(number),contour and other information of the cluster,which has strong application value.
