A deconvolution method for pulsed coherent radars


  • Paul Lehmann


The effects of a necessarily limited transmission and reception bandwidth upon a pulsed coherent radar experiment can be partially overcome by the use of the deconvolution method described. Unlike ‘conventional’ techniques, an accurate knowledge of the radar system pulse response is not required to estimate the propagation delays of reflected pulses (echoes). However, a knowledge of the complex pulse response facilitates the simulation (Monte Carlo) of a ‘generalized’ echo structure model from which a deconvolution analysis can yield 95% confidence limit estimates for the calculated echo delays. Simulation results are presented showing dependence between the errors in delay estimates, the form of pulse response, and deconvolution control parameters.
