ABSTRACT:
Waveforms received at a transmitter antenna are Fourier transformed to extract waveform spectrums. These spectrums are enhanced so as to provide near uniform pulse spectrum sidelobe amplitudes. These enhanced side lobe waveforms are then Fourier transformed. The result is conversion of received waveform time domain discontinuities into impulses. The energy in the received waveform is retained. The conversion to impulses provides processing gain. Correlation processing exploits finite differences in both spectrum and impulse conversion characteristic of radar targets, jamming and clutter.
