The maximum radar cross section of a resonant linear λ / 2 dipole is approximately 0.86λ2 . For a monostatic system (i.e., transmitter and receiver at the same location), find the received power (in W) if the transmitted power is 100 W, the distance of the dipole from the transmitting and receiving antennas is 100 m, the gain of the transmitting and receiving antennas is 15 dB each, and the frequency of operation is 3 GHz. Assume a polarization loss factor is -1 dB.
What is the minimum detection distance, if the radar's sensitivity is 1 nW?
