Radar echo protege against the rain and method of protection of a radar echo against the rain

摘要

The radar is designed to identify and dispose of the signals relating to the echo of rain. For this purpose, the radar works in circular polarization, with a recurrence at the next, the direction of polarization in the transmission and reception, alternately identical and opposite. The identification of the signals relating to the echo processing is done by a comparator 16, which compares the sum of the video signals relating to the same distance quanta for two successive recurrences, the identification criterion since a significant difference between the levels of the signals compares. A switch 17 controlled by the comparator 16 ensures the elimination of parasitic signals. / p & & p & application to the field of radar.
