Here, [P.sup.obs.sub.c] is the observed radar clutter power and [P.sub.c] is the modeled radar clutter power.
It is capable of modeling texture component of radar clutter with different degrees of heterogeneity and has been widely applied in heavy-tailed radar clutter modeling, such as SAR clutter [26,27], C-band scanning radar [28], etc..
However, the increasing heights mean more radar clutter.
Such unwanted returns are known as radar clutter. Clutter is displayed to a controller as "interference" and is primarily a problem for air defence and airport radar operators because it occurs more often at lower altitudes.
Because they operate tens of thousands of feet above the Earth, they are not as subject to radar clutter, and are thus well suited to detect low flying, and in some cases stealthy, aircraft.
Chapter 2 explains the effects of platform motion on both CW and pulsed radar clutter.
This decrease in response times for the evening shift is probably attributable to differential radar clutter. During the first two days of Session 1, there was considerable radar clutter in the southern and southeastern zones.
* ECM time-gated waveforms must be synchronized with the radar waveform to avoid signal "walk through" RFI and resultant ECM cross modulation of radar clutter return signals.
Moreover, to be able to optimize the signal processing under different conditions, the radar system designer also needs to have a detailed analysis of wideband monopulse radar clutter properties.
The increase in the number of wind farms has raised serious concerns in the radar community due to the radar clutter produced by wind turbines.
Secondly, a pure radar clutter (a return signal without target) may agree with a fractal model commendably, but the existence of a target will change its fractal characteristics remarkably even if being in a environment with strong clutters.
A ship in a seaway is surrounded by the radar clutter created by waves.
