Abstract

Fourier synthesis method of waveform generation for ultra wideband (UWB) radar overcomes several disadvantages of traditional impulse generation. In this method a signal is generated in frequency domain by summing the relatively low power harmonics of the desired signal instead of generating it by a single high power source in time domain. In this paper waveform generation is extended beyond simple baseband periodic pulses. Method for generation of complex amplitude coded baseband waveforms with accurate control of pulse shape and pulse repetition interval is described. This waveform allows pulse compression and coherent integration of UWB signals and thus further reducing the need for very large power sources which may be required for conventional impulse radar implementation. The paper also presents a UWB radar concept which incorporates frequency domain waveform generation. Signal processing issues for target detection are also addressed.
