Challenge Problems
Push your limits with challenges.
Question 1
An FMCW radar has a sweep bandwidth of 500 MHz, and the duration of the up-chirp is 2 ms. If the beat frequency detected is 25 kHz, calculate the range and the average radial velocity of a target at this beat frequency.
💡 Hint: Use the formulas appropriately and remember c is approximately 3 × 10^8 m/s.
Question 2
Explain the trade-offs in choosing PRF for a radar system that requires a balance between range and velocity accuracy.
💡 Hint: Discuss implications for operational performance based on distance measurement and calculation.
