What is the effect on frequency when an object moves towards the RADAR?

Explanation:
When an object moves towards the RADAR, the frequency of the reflected signal is affected due to the Doppler effect. Specifically, as the object approaches the RADAR, the waves emitted by the RADAR compress, leading to an increase in frequency. This phenomenon is known as "Doppler shift," where the frequency increases for an approaching object and decreases for an object moving away. Hence, an increase in frequency is the correct and expected outcome when the object is moving towards the RADAR, allowing for accurate speed and distance calculations.
