CW in radar means a continuous wave. It refers to a type of radar system that continuously emits an electromagnetic signal at a constant frequency. The primary use of CW radar is to measure the speed of moving objects by detecting changes in the frequency of the reflected signal due to the Doppler effect.
CW RF, or continuous wave radio frequency, refers to a type of radio signal that is transmitted continuously at a fixed frequency and amplitude. This mode of transmission is used in various applications such as radar systems and communication where a constant signal is required.
The difference between CW radar and MTI (moving target indicator) radar is their functionality. The CW radar continuously emits a signal to measure the Doppler shift and determine the speed of moving objects. MTI radar, on the other hand, is designed to detect and filter out stationary clutter to focus on moving targets. MTI radar uses techniques to differentiate between moving and stationary objects, often using pulse transmission for better target detection.
CW guidance refers to a type of guidance system that uses continuous wave signals to direct and control the trajectory of a missile or other guided vehicle. The system continuously transmits a signal that is reflected by the target, and adjustments are made based on shift or changes in the Doppler signal to guide the vehicle precisely to the target.
