Push your limits with advanced challenges
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.
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.
