Introduction to Random Signal Radar

Random signal radar refers to radars that transmit a microwave noise signal or a waveform modulated by a low-frequency random noise. In contrast to conventional radars whose waveforms transmit deterministic and periodic signals, random signal radars use noise-like waveforms that have nondeterministic and nonperiodic properties. Noise-like waveforms give random signal radars some special advantages over conventional radars. This lecture introduces the fundamental concepts of random signal radars as well as their characteristics and advantages. In addition, it addresses the relationship between ultrawideband (UWB) radar and random signal radar to show how we can gain significant benefits by combining UWB technology and random signal radar.
