A frequency domain approach to the 

 -pulse radar target discrimination scheme is introduced. This approach is shown to allow easier interpretation of 

 -pulse convolutions via the 

 -pulse spectrum, and leads to a simplified calculation of pulse basis function amplitudes in the 

 -pulse expansion. Experimental evidence obtained using aircraft models verifies the single-mode discrimination scheme, as well as the aspect-independent nature of the 

 -pulse technique. This leads to an integrated technique for target discrimination combining the 

 -pulse with single mode extraction waveforms.
