Consider an airborne radar system flying at an altitude of 20 km with the radar look-angle set to ψ = 40°. The output power of the system is initially 100 W. Later, the aircraft increases its altitude to 30 km and re-images the same target using the same look-angle. Assuming all other parameters are unchanged, what transmit power is required at 30 km altitude to maintain the same received power as at 20 km altitude?
