Chapter 9, Problem 29P
The configuration shown in Fig. P9.29 depicts a satellite repeater with two antennas, one pointed towards the antenna of ground station 1 and the other towards the antenna of ground station 2. All antennas are parabolic dishes, antennas A1 and A4 are each 4 m in diameter, antennas A2 and A3 are each 2 m in diameter, and the distance between the satellite and each of the ground stations is 40,000 km. Upon receiving the signal by its antenna A2, the satellite transponder boosts the power gain by 80 dB and then retransmits the signal to A4. The system operates at 10 GHz with Pt = 1 kW. Determine the received power Pr. Assume all antennas to be lossless.
