Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A radar system uses classical matched filtering with known signal energy of 5 μJ under conditions of AWGN with a power spectral density of 6 x 10^-19 W/Hz. Calculate the maximum SNR output.

💡 Hint: Apply the SNR formula where energy and noise values are involved.

Challenge 2 Hard

Discuss how variations in impulse response can affect the performance of a radar system and provide an example.

💡 Hint: Consider what happens when the filter is misaligned with the target signal.
