A new method of HRR profile formation based on multiple radars LFM signal fusion

Abstract

In this paper, the authors present a new method of HRR profile formation based on the LFM signal fusion of the multiple radars with multiple frequency bands. The principle of the multiple radars signal fusion improving the range resolution is analyzed. During the fusion process, the B-splines interpolation and an entropy-minimization principle based phase compensation algorithm are applied. The theoretical analysis and simulations results show the proposed method can effectively increase signal bandwidth and provide a high resolution range profile
