problem 1: For an antenna half power beam width is 3 and scan rate is 30 /sec. Compute the target illumination period. If R_{unamb} = 100 Km. Compute the number of received pulses every illumination period.
problem 2: How is multiple time around echoes distinguished from the unambiguous echoes?
problem 3: What do you mean by the term false alarm?
problem 4: Define the term radar cross section of target.
problem 5: How does integration of the radar pulses enhance the detection capability of the radar?
problem 6: In a radar receiver P_{fa }= 1.05*10 - 10BIF = 1 MHz. Determine the average false alarm time tolerable? For the same P_{fa}, how many dbs above the rms voltage, the threshold voltage must be?
problem 7: Describe the importance of radar cross section of targets.
problem 8: Illustrate the operating frequency, power requirements and expected range of an actual radar system.
problem 9: The noise entering the IF amplifier is white Gaussian. If threshold to noise ratio is 14 dB, determine the probability of false alarm?
problem 10: Why do we choose higher radar frequencies for the meteorological radars?
