Which modulation is most commonly associated with radar signals?

Pulse Modulation (PM) is closely associated with radar signals because radar systems typically operate by transmitting short bursts or pulses of radio frequency energy. These pulses allow radar to effectively measure distances and analyze the speed and position of objects. The ability to send and receive these quick pulses aids in gathering vital information about the targets, making pulse modulation an ideal choice for radar applications.

In radar systems, the use of pulsed signals helps in distinguishing between different targets as it allows for time separation of echoes from the transmitted signals. This characteristic is essential for effectively interpreting the data received from objects that may be at varying distances.

Other modulation methods like Frequency Modulation (FM) and Amplitude Modulation (AM) are more suited for audio and communication signals rather than the specific needs of radar operations, which prioritize precise timing and distance measurement. Digital Modulation, while used in some modern radar systems, does not define radar technology as a whole in the way that pulse modulation does.
