Localization Strategies for Multiple Point-Like Radar Targets

摘要: In this correspondence, we focus on the design and analysis of schemes aimed at estimating position multiple point-like targets that fall among three adjacent samples matched filter output (typically present in processing chain a radar). To end, exploit spillover targets' energy to range cells. The number (and corresponding Doppler frequency shifts) is assumed be known. Moreover, suppose received useful signals can modeled terms vectors known up deterministic parameters they are embedded correlated Gaussian noise with unknown covariance matrix. For estimation purposes assume set secondary data, free signal components, but sharing same matrix cells containing returns, available. analysis, also comparison possible competitor, proves superiority multitarget respect single target ones, even under reasonably mismatched scenarios.
