The radar pulse loses energy as they travel in the space at a rate proportional to the beamwidth. The beam spread significantly by the time it reaches the earth. Synthetic aperture radars are the solution to this problem since the outcome will greatly change. Synthetic aperture radars were designed to circumvent natural aperture radar limitations. Such systems obtain a strong azimuth resolution which is not based on the slant but does use small antennas and fairly long wavelengths.
