4.4. An L-band radar has the following specifications: operating frequency

, operating bandwidth , noise figure , system losses , time of false alarm , detection range , probability of detection , antenna gain

, and target RCS .

(a) Determine the PRF , the pulse width , the peak power , the probability of false alarm , and the minimum detectable signal level .

(b) How can you reduce the transmitter power to achieve the same performance when 10 pulses are integrated noncoherently?

(c) If the radar operates at a shorter range in the single pulse mode, find the new probability of detection when the range decreases to .
