Abstract	Radar systems have long been plagued by poor cross range (azimuthal) resolution due to the standoff range of the sensors and limitations of aperture size and beamwidth. This problem is especially an issue for sensors operating in the VHF and UHF bands due to the large physical aperture required to achieve reasonable beamwidths. A coherent sparse sensor network can improve both angle and range resolution of radar systems while limiting the required system bandwidth. In fact, a key advantage of the proposed technique is that the target localization achievable, both in range and cross range, is not limited by the bandwidth or aperture of the individual receiver systems employed in the sensor network. This paper discuss the benefits and performance of coherent sparse aperture techniques. In addition the impact of system errors on performance and error mitigation techniques are discussed.
