Describe how Frequency Modulated Continuous Wave (FMCW) differs from traditional Pulse Radar.

Frequency Modulated Continuous Wave (FMCW) radar distinguishes itself from traditional pulse radar primarily through its method of signal transmission and data processing. In FMCW systems, the radar continuously emits a signal whose frequency varies over time, typically in a sawtooth pattern. This frequency modulation allows the radar to measure both the time delay of the received signal and the Doppler effect, enabling it to simultaneously determine both range and relative velocity of a target. This dual capability is one of the principal advantages of FMCW radar, making it more versatile in specific applications such as automotive and environmental sensing.

Other options address different aspects of radar systems. For instance, while it is true that FMCW transmits continuous signals as opposed to the short bursts used in traditional pulse radar, this statement does not capture the significant aspect of frequency variation that enables simultaneous range and velocity measurement. Similarly, stating that FMCW is only useful for measuring speed is inaccurate, as it is adept at measuring both range and speed. Lastly, while beam width can differ based on specific system design characteristics, the difference in signal transmission and data processing techniques is more defining of the unique capabilities of FMCW compared to traditional pulse radar.
