Question: A certain radar has the following specifications: pulse width t'lus, antenna beam width 2 = 1.5, and wavelength = 3cm. The radar antenna is 7.5m

A certain radar has the following specifications: pulse width t'lus, antenna beam width 2 = 1.5, and wavelength = 3cm. The radar antenna is 7.5m high. A certain target is simulated by two point targets (scatterers). The first scatterer is 4m high and has RCS = 20m. The sec- ond scatterer is 12m high and has RCS 2 = 1m. If the target is detected at 10Km, compute

(a) SCR when both scatterers are observed by the radar;

(b) the SCR when only the first scatterer is observed by the radar. Assume a reflec- tion coefficient of -1, and = -30dB.
