We introduce a sparsity based deconvolution scheme to improve the range resolution of passive bistatic radar (PBR) systems. The two-dimensional matched filter output of a PBR system is further analyzed as a deconvolution problem. The deconvolution algorithm is based on making projections onto hyperplanes representing the time delay of a target and the epigraph set of a convex cost function such as the l<inf>1</inf> norm. The iterative algorithm is globally convergent because all constraint sets are closed and convex. Simulation results in a FM based PBR system are presented. The proposed method performs better than frequency domain deconvolution methods. © 2015 IEEE.

Range resolution improvement in passive bistatic radars using nested FM channels and least squares approach Arslan, M.T.; Tofighi, M.; Sevimli, R.A.; Çetin, A.E. (SPIE, 2015)One of the main disadvantages of using commercial broadcasts in a Passive Bistatic Radar (PBR) system is the range resolution. Using multiple broadcast channels to improve the radar performance is offered as a solution to ...
Arslan M.T.; Tofighi M.; Ã etin A.E. (Springer-Verlag London Ltd, 2016)FM-based passive bistatic radar (PBR) systems suffer from low range resolution because of the low baseband bandwidth of commercial FM broadcasts. In this paper, we propose a range resolution improvement method using ...
