Clutter Analysis for a Land-Based, MTI Radar Consider a land-based MTI radar system. Calculate the clutter-to-noise ratio with and without MTI processing. First setup the radar and MTI processing parameters. % Radar propertiesfreq = 1.5e9;% L-band frequency (Hz)anht = 15;% Height (m)ppo...
This method imposes no restrictions on the transmitter, reduces both the sampling and processing rates and exhibits linear signal-to-noise ratio improvement with the number of pulses. Here we extend previous work on sub-Nyquist pulse-Doppler radar by incorporating a clutter removal algorithm operating...

In this paper, we present simulation results that show the effect of the two-way peak sidelobe levels on the signal-to-interference-plus-noise ratio (SINR) loss curve, as a function of clutter-to-noise ratio, for a monostatic space-based ground moving target indicator (GMTI) radar operating...
