WebWe consider four effects relevant to the determination of the ratio of radar signal to clutter and noise. These effects are atmospheric turbulence, target fluctuations based on the Swerling models, zero-mean Gaussian background and receiver noise, and lognormal-distributed clutter. Radar return signal levels are affected by target fluctuations and … WebJun 7, 2004 · Radar clutter is distinguished from thermal noise by being caused by random reflection of transmitted electromagnetic energy. This paper considers what may be done by means of linear filtering to improve the detection of small radar signals in the presence of this clutter. Defining the signal‐to‐clutter ratio as the ratio of the peak signal to the rms …
