Challenge Problems
Push your limits with challenges.
Question 1
An FMCW radar with a linearly swept bandwidth of 500 MHz and a sweep time of 4 ms detects a beat frequency of 30 kHz. Calculate the range to the target.
💡 Hint: Remember to carefully analyze unit conversions!
Question 2
Given that a target is moving towards the radar, resulting in a Doppler frequency shift of 880 Hz and an average carrier frequency of 77 GHz, find the target's radial velocity.
💡 Hint: Revisit the fundamental concepts of Doppler shift!
