Challenge Problems
Push your limits with challenges.
Question 1
A vehicle equipped with FMCW radar emits a frequency chirp starting at 77 GHz and sweeps up to 79 GHz over a 10 ms period. Calculate the beat frequency for a stationary target if the echo signal returns after 15 ms.
💡 Hint: Recall that the beat frequency is linked to the delay and the modulation characteristics.
Question 2
Explain how FMCW radar could be adapted for industrial use in material thickness measurement and the role of beat frequency in this application.
💡 Hint: Reflect on the principles of echo and modulation from distant materials.
