ISRO Electronics & Communication (ECE) 2014 - Question 77

All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2014

Topic: Radar and Navigation

Range resolution of a Linear Frequency Modulated pulse compression radar depends on which of the following factors

  • A. Radiated power
  • B. Antenna size
  • C. Center frequency of the radar
  • D. Bandwidth of the transmitted pulse

Answer: D. Bandwidth of the transmitted pulse

Explanation: Range resolution is inversely proportional to the bandwidth of the transmitted pulse. For a Linear Frequency Modulated (LFM) pulse compression radar, the resolution improves as the swept bandwidth of the chirp increases.
