Non Cooperative Radar Target Identification Using Exponential Single-Mode Extraction Pulse

Abstract

We present a new contribution to the single-mode extraction pulse (S-pulse) technique. The S-pulse technique uses the natural frequencies of the target as discrimination features in such a way that the field scattered by a target after it passes through a S-pulse designed for this specific target has the form of a damped sinusoid. The S-pulses are usually constructed as a linear combination of cosine or polynomial basis functions, expressing a S-pulse function as a linear combination of these functions and fixing the linear parameters with conditions on the Laplace transform. The S-pulses are synthesized using complex exponential basis functions within which are extra parameters that can be used to tune their discrimination capabilities. The proposed S-pulses are compared with the ones in the literature using thin conductive wires as simulation targets and in this way we show that there is a distinct improvement in their discriminatory capacity.
