Improving angular resolution algorithm based on Landweber’s iteration for scanning radar systems

Abstract

Scanning radar systems have extensive and significant applications, but theirs angular resolution usually is low because of many constraints. In this paper, a Landweber iteration algorithm of improving the angular resolution is proposed. Firstly, a signal model in the azimuth of the scanning radar system is illustrated. Then the Landweber algorithm is derived in theory. At last, Simulations and real radar data experiments show that the algorithm can effectively improve the angular resolution of the scanning radar system.
