← ScienceWhich outcome occurs when a pulsed radar system's clock drifts during signal propagation?
A)Range measurement errors greatly increase✓
B)Target resolution remains fairly consistent
C)Signal frequency maintains absolute precision
D)Transmitter power perfectly self-compensates
💡 Explanation
Range error increases because clock drift causes errors in time of flight calculations via the Doppler Effect, a frequency shift. This is called range-Doppler coupling caused by timing imprecision therefore the range is inaccurate rather than constant at high frequencies.
