TLDR
The effect of limiting on the spectrum of Gaussian noise is computed where the noise has a Gaussian spectrum before limiting, and the output spectral density is plotted for various noise-to-limit level ratios.Abstract:
The effect of limiting on the spectrum of Gaussian noise is computed where the noise has a Gaussian spectrum before limiting, and the output spectral density is plotted for various noise-to-limit level ratios. A decibel scale displays the spectral spreading due to limiting with an accuracy not available in previously published data. The results have application to radar and sonar signal processors which attempt to detect targets in clutter.read more

Moving Target Indication Radar
TL;DR: MTI (Moving Target Indication) radar systems have been built for many years, based on sys-tem concepts evolved in the early 1950's as discussed by the authors, and many of the existing systems are very successful, even though their performance, measured in terms of MTI improvement factor or subclutter visibility, often falls far short of the performance predicted from linear theory.

Radar Counter-Countermeasures
TL;DR: In order for a surveillance or tracking radar to operate in a general-type countermeasures environment, no single radar countermeasure threat can be assumed dogmatically.

The correlation function of smoothly limited Gaussian noise
TL;DR: In this paper, the correlation function of smoothly limited Gaussian noise is compared with the correlation of extremely clipped Gaussian noises, where the limiting function is assumed to have the shape of the error integral carve.
