K-pulse estimation from the impulse response of a target

A simple and general method is used to estimate the K-pulse of a target from its Fourier synthesized impulse response. The approach is based on minimization of energy content outside the K-pulse response duration. The method is simple because it only deals with Dirac delta functions in integrals. It is general because the method only manipulates samples of a continuous function as a computer does. The method does not require a priori information on the target poles. Results obtained from Fourier synthesized data show excellent convergence for the K-pulses. Furthermore, dominant poles of the target can be extracted from the approximated K-pulse. The pole-extraction method is also discussed in association with some results.
