Sidelobe comparison of golay and PRBS codes for subsurface radar applications

Ultrawideband (UWB) radar is an evolving area of great interest with many potential defense and civilian applications. Broadly, UWB waveforms could be classified into non-random and random waveform categories; both nonlinear and linear frequency modulated (LFM) and typical coded waveforms fall in the former category, while random noise-like and pseudorandom noise-like waveforms are the examples of the latter. Since the waveforms transmitted by the radar systems can affect the target detection, accuracy, resolution, ambiguities, and clutter rejection, etc., there is a great interest to design and implement various transmit waveforms with predetermined criteria.
