Now that the scene and the radar system are defined, generate returns from the land surface with the clutterGenerator method. Rdrplat.Sensors = rdr Generate the Datacube PulseCompress = phased.RangeResponse( 'RangeMethod', 'Matched filter'. MatchingCoeff = getMatchedFilter(rdr.Waveform) Rdr.Waveform = phased.LinearFMWaveform( 'SampleRate',fs, 'PulseWidth',tpd. = freq ДЄntennaGain = aperture2gain(aperture,lambda) % Define transmit and receive antenna and corresponding parametersДЄnt = phased.SincAntennaElement( 'FrequencyRange', 'Beamwidth',antbw) % Set receiver sample rate and noise figure Rdr = radarTransceiver( 'MountingAngles',mountAngles, 'NumRepetitions',1) Plot the reflectivity map to see the assignments Otherwise, set reflectivity values to woods. For terrain values above 100 meters, assign reflectivity values for wooded hills. Land types supported are soil, grass, shrubs, and short vegetation.ДЇor this example, use the default Barton model, since it has such a large number of land types. Ulaby-Dobson: Semi-empirical model for low to medium grazing angles over frequencies in the range from 1 to 18 GHz. Land types supported are desert, farm, woods, jungle, rolling hills, and urban. Nathanson: Empirical model for low to medium grazing angles over frequencies in the range from 1 to 36 GHz. Land types supported are desert, farm, woods, and mountains.

Morchin: Mathematical model for high grazing angles over frequencies in the range from 300 MHz to 8 GHz.

Land types supported are soil, grass, tall grass, trees, and urban. GIT: Semi-empirical model for medium grazing angles over frequencies in the range from 3 to 15 GHz. Land types supported are low-relief rural, low-relief forest, farm, desert, marsh, grassland, high-relief rural, high-relief forest, mountains, urban, low-relief urban. This is the default model.Д«illingsley: Empirical model valid for low grazing angles over frequencies from 3 MHz to 12 GHz. Land types supported are rugged mountains, mountains, metropolitan, urban, wooded hills, rolling hills, woods, farm, desert, flatland, and smooth. Land types supported are urban, high-relief, and low-relief.Д«arton*: Mathematical model supporting medium grazing angles over frequencies in the range from 1 to 10 GHz. APL: Mathematical model supporting low to high grazing angles over frequencies in the range from 1 to 100 GHz.
