2 A rectangular search radar antenna is 2.5m wide by 1.4m high. It has an azimuth length efficiency of 0.78 and elevation length efficiency of 0.65 and is operating at 13GHz. For this antenna, calculate: a. Azimuth and elevation beam widths; b. Effective aperture; and Gain c. If the elevation efficiencies are improved to 100%, what is the effect on beam width? Justify your answer.
