In a RADAR system, which component adjusts the shape and width of pulses?

In a RADAR system, the modulator is responsible for adjusting the shape and width of the pulses that are transmitted. The modulator takes a continuous wave signal and converts it into a series of pulses, controlling various aspects such as their duration and rise and fall times.

By tailoring these pulse characteristics, the modulator plays a crucial role in determining how effectively the radar system can detect and analyze targets. The shape of the pulse can affect the resolution of the radar, while the width of the pulse influences the radar's range resolution and ability to distinguish between closely spaced targets.

In contrast, other components mentioned, such as the pulsing oscillator, generate the frequency of the signals but do not directly shape the pulse. The pulsed response filter processes the received signals to filter out noise and unwanted frequencies, and the pulsed amplifier strengthens the transmitted or received pulses but does not shape their form. Therefore, understanding the function of the modulator is pivotal for grasping how RADAR systems operate effectively.
