Rain Radar-Introduction of Common Rain Radar

The earliest rain radar 7 1 1 in China is a small rain radar made in China. The wavelength is 3.2cm, the antenna diameter is 1.5 m, the antenna gain is 38dB, the beam width is 1.5 degrees, the transmitted pulse power is 75KW, the pulse width is 1 microsecond, and the pulse repetition frequency is 400HZ. The minimum measurable power is 98dB mw. Equipped with PPI (Plane Position Indicator) and RHI (Distance Height Display) and A/R display. This is the earliest rain radar produced in China, with more than 300 sets, which are equipped in meteorological radar stations, airports, seaports, salt fields and other places all over the country.

7 12 radar

A domestic rain radar. The wavelength is 3.2cm, the antenna aperture is 5.5 m (vertical) and 1. 1 m (horizontal), the beam width is 0.45 degrees (vertical) and 2 degrees (horizontal), the transmitted pulse power is 180KW, the pulse width is 1 microsecond, and the pulse repetition frequency is 30. Equipped with PPI (Plane Position Indicator) and RHI (Distance Height Display) displays. In addition, it is equipped with HCT- 1 image transmission equipment with a transmission distance of 50 kilometers. This kind of radar is actually a variant of altimeter radar, so its vertical lobe is very narrow, which is suitable for measuring the height and bottom of cloud bottom and cloud top more accurately, so it is often used in airports.

7 13 radar

A domestic rain radar. The wavelength is 5.6 cm, the antenna diameter is 3.7 m, and the antenna gain is 38 dB. The beam width is 1.2 degrees, the transmitted pulse power is 250kw, the pulse width is 2 microseconds, the pulse repetition frequency is 200HZ, the minimum measurable power is-107 dB MW, and the maximum detection distance is 400KM. Equipped with PPI (Plane Position Indicator), RHI (Distance Height Display) and RHI (Distance Height Display) and A/R display, and equipped with video signal processor, it can accurately measure precipitation. Mainly equipped in regional meteorological stations and some provincial meteorological stations, as well as meteorological research institutions.
