Challenge Problems
Push your limits with advanced challenges
Consider a radar system using an FMCW signal with a beat frequency of 15 kHz and a sweep rate of 300 MHz/s. Calculate the range to the target.
💡 Hint: Ensure you have all variables correctly defined before plugging them into the formula.
If a mobile object moves towards the radar causing a Doppler frequency shift of 5 kHz, how would you calculate the radial velocity from this frequency shift?
💡 Hint: Understanding how Doppler effects factor into your calculations is key.
