Abstract :
Azimuth target resolution is of crucial importance in many applications of radar. The primary radar parameter affecting the azimuth resolution is the antenna beamwidth. However, in practice, standard signal processing techniques require the distance between targets to be more than one resolution cell. This can prove inadequate for several relevant applications. This paper describes the results obtained from experiments aimed at testing the capabilities of angular resolution between targets separated by less than the beamwidth in azimuth by means of linear minimum mean square error, LMMSE, -based processing. Results show the capabilities of this technique of separating targets in such a scenario. The processing scheme shows a strong improvement in the resolution capability with respect to standard techniques.
