Question

2. A pulsed airborne radar operating at 12GHz has a peak power of 1 kW and uses an antenna with directivity of 2100. Total monostatic path loss is 1.8. The radar views a surface at normal range of 3 km and grazing angle of t/2. The available received clutter power (Sre) is 1.1x10-11 What is the effective surface scattering area of σ,-2.5x10-4 for the surface? (10pts) a) b) If the radar and target orientation are changed such that the grazing angle is now 30° and the foot print beamwidths are фв-1.50 and B-10, what is the new effective illuminated surface such that half (0.5) of the foot print is illuminated? (Assume Case 1) (10pts)
