Continuous-wave radar
Continuous-wave radar is a type of radar system where a known stable frequency continuous-wave radio energy is transmitted and then received from any reflecting objects. Continuous-wave (CW) radar uses Doppler, which renders the radar immune to interference from large stationary objects and slow moving clutter.CW radar systems are used at both ends of the range spectrum. Inexpensive radio-altimeters, proximity sensors and sport accessories that operate from a few dozen feet to several kilometers Costly early-warning CW angle track (CWAT) radar operating beyond 100 km for use with surface-to-air missile systems↑ ↑
