Which risk is amplified in a pulsed radar system when the pulse duration approaches the reciprocal of a target's Doppler broadening?

💡 Explanation

Gain reduction arises because the spread introduced overlaps the matched filter bandwidth; therefore, the returned energy misses optimal detection, rather than different errors given pulse properties, because the matched filter integrates most efficiently when receive bandwidth matches signal bandwidth.
