Repair and Maintain a Doppler radar

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns,^[1] radiology and healthcare (fall detection and risk assessment, nursing or clinic purpose^[2]), and bistatic radar (surface-to-air missile).
