How does target velocity impact the Doppler effect observed in Pulse Radar?

The choice indicating that a faster target leads to a greater frequency shift in the reflected radar signal is correct due to the principles underlying the Doppler effect. In the context of pulse radar, the Doppler effect refers to the change in frequency of the radar signal that occurs when there is relative motion between the radar and an object (target).

When a target is moving towards the radar, the frequency of the reflected signal increases, leading to a phenomenon known as a positive Doppler shift. Conversely, if the target is moving away, the frequency decreases, resulting in a negative Doppler shift. The magnitude of this frequency shift is directly proportional to the velocity of the target. Thus, as the speed of the target increases, the rate at which the frequency changes also increases, making it easier to detect and measure the target's speed accurately.

This principle is critical in radar applications, as the measurement of this frequency shift provides essential information about the target's velocity. In contrast, the other options suggest incorrect interpretations of the relationship between target velocity and the frequency shift, failing to consider the fundamental aspects of the Doppler effect.
