7. A radar antenna mounted on a Mars rover with an effective area of 1 mºis transmitting 1 kW of 4 GHz to the earth from Mars. An antenna with an effective area of 10 m² on the earth is to receive the signal from the Mars rover. Calculate: (a) The minimum transmitting power needed for the antenna on the Mars rover to have an E field of 0.1 mV/m on the earth antenna. (20 points) (b) The maximum range the radar on the Mars rover can have for the earth radar to detect a power of 1 pW. (20 points) (c) The minimum antenna area on the earth radar to detect a H field of 0.1 mA/m from the Mars rover. (20 points)
