An approximate K- pulse estimation technique based on Legendre polynomial expansions and late-time target response energy minimizations is formulated and applied to both high-Q and low-Q targets. The targets have varying degrees of geometrical complexity. The complex natural resonant (CNR) frequencies of the test targets are numerically extracted as frequency domain zeros of the resultant K- pulses. The validity of the K- pulse estimation results is demonstrated by means of target discrimination examples at arbitrarily chosen combinations of aspect and polarization. Comparisons of the extracted CNR frequencies with other results are also used to verify the K- pulse synthesis results wherever a priori information on a test target's natural resonances is available.
