A complete set of scans takes around 5 minutes to complete. Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. CAUTION: Radar images from Weather Underground may not be updating. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. Satellite & radar images with a variety of views covering the Pacific, USA & Canada. The radar instrument receives a signal from this reflected energy during its listening period.

A small fraction of the scattered energy is directed back toward the radar. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The radar emits a burst, or pulse, of energy.
