Which consequence results when a radar system attempts coherent signal processing with excessive phase noise?

💡 Explanation

Excessive phase noise corrupts the reference signal used in matched filtering. This spectral dispersion reduces coherent gain in signal processing, because the reflected signal energy is spread across multiple frequency bins, therefore lowering sensitivity and decreasing target detection probability, rather than improving resolution.
