Coherent integration angle for SAR
Estimate the coherent integration angle of a side-looking airborne synthetic aperture radar (SAR) with an operating frequency of 10 GHz and a cross-range resolution of 1 m. Assume the azimuth broadening factor to be 1.3.
f = 10e9; azres = 1; azb = 1.3;
Compute the coherent integration angle.
lambda = freq2wavelen(f); ciang = sarintang(lambda,azres,azb)
ciang = 1.1165
lambda— Radar wavelength
Radar wavelength in meters, specified as a positive real scalar or a vector.
azres— Image azimuth or cross-range resolution
Image azimuth or cross-range resolution in meters, specified as a positive real scalar or a vector.
azb— Azimuth impulse broadening factor
