2.16. A certain radar has losses of 6dB and a receiver noise figure of 8dB. It has the requirement to detect targets within a search sector that is 360 degrees in azimuth and from 5 to 65 degrees in elevation. It must cover the search sector in 2 seconds. The RCS of the targets of interest is 5dBsm and the radar requires 20dB of signal-to-noise ratio to declare a detection. The required detection range of the radar is 75Km. What is the average power aperture that the radar must have to satisfy the above search requirements
