Question

A ground-based air-surveillance radar operates at a frequency of 1300 MHz (L-band). Its maximum range is 200 km for the detection of a target with a radar cross-section of 10 m^2. Its antenna is 12 m wide by 4 m high, and the aperture efficiency is 0.65. The receiver minimum detectable signal is 0.1 pW. Determine: (a) Antenna effective aperture and antenna gain (numerically and in dB). (b) Peak transmitter power.

Step 1

The effective aperture \( A_e \) of an antenna can be calculated using the formula: \[ A_e = \eta A_p \] where \( \eta \) is the aperture efficiency and \( A_p \) is the physical aperture area. The physical aperture area \( A_p \) for a rectangular antenna is Show more…
