What is a CW system?
A CW system, or continuous wave system, is a type of radar or communications system that continuously emits a signal at a constant frequency. It is used primarily for applications where constant monitoring and measurement of moving objects is required, such as speed detection.
CW works by emitting a continuous electromagnetic wave and measuring the Doppler shift in the frequency of the reflected wave. Doppler shift, caused by the movement of the target, provides information about the speed of the object, but not its distance.
How does CW work?
CW stands for continuous wave, which refers to a type of signal that is uninterrupted and maintains a constant frequency. ACW, or alternating continuous wave, refers to a variation where the signal alternates between different frequencies or amplitudes, but still involves continuous wave transmission.
What is CW and ACW?
The principle of CW is to transmit a wave continuously and detect any frequency shift in the reflected signal. This change, caused by the movement of objects, makes it possible to measure their speed. CW systems do not measure distance directly, because they do not use delay measurements.
The CW radar system is a type of radar that operates using continuous wave transmission. It continuously emits a signal and detects changes in the frequency of the returned signal due to the Doppler effect, which provides information about the speed of moving objects. It is not designed to measure the distance of targets.
