Distortion Effects in Phase-Coded Radars with Digital Signal Processing.
Abstract
The effects of single-bit digital signal processing upon the output of a phase-coded radar are considered. When a point target is viewed, the system response is approximately linear as long as the input signal-to-noise ratio is small compared to unity. The output signal-to-noise ratio is 2/pi times the value it would have for a truly linear analog system. When a target extending across R + 1 range bins is viewed, the system response will be linear as long as the input signal-to-noise ratio is small compared to 1/R. Theoretical results are compared with a Monte Carlo simulation. (Modified author abstract)
