The effect of the clutter-to-noise ratio on the performance of a Doppler filter is considered. Clutter is assumed to have a power level which is unknown and varies in range. The assessment of the performance of a Doppler filter is based on the gain of the filter, which is the normalized...
Calculating Clutter-to-Noise Ratio Consider a horizontally polarized maritime surveillance radar system operating at 6 GHz (C-band). Define the radar system. Get % Radar parametersfreq = 6e9;% C-band frequency (Hz)anht = 20;% Height (m)ppow = 200e3;% Peak power (W)tau = 200e-6;% ...
Calculate the RCS of a clutter patch and estimate the clutter-to-noise ratio (CNR) at the receiver. Assume that the patch has a normalized radar cross section (NRCS) of 1 m²/m² and is 1.0 km away from the radar system. The azimuth and elevation beamwidths are 1° and 3°, re...
