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