Technical field
The invention belongs to meteorological field, relate to the modifying device of a kind of radar angle of pitch control, relate in particular to the accurate pitch rotation of a kind of shadow radar mechanism.
Background technology
For conquering meteorological disaster, artificial rainfall eliminating hail, becomes unfavorable into favourable.Meteorological department surveys weather with general Mini-type meteorological radar, and the cloud layer of monitoring sky process, carries out in real time rainmaking and eliminate hail, and antenna is intervened.
Weather modification, rainfall hail mitigation needs the thickness of height, orientation, distance and the cloud layer of accurate remote measurement cloud layer.Whether telemetry is accurate, and can be related to enforcement rainmaking or hail mitigation successful.
Radar is for radiation and receives electromagnetic wave and determine the equipment of its detection direction.Radar must be radiated the direction that needs irradiation concentration of energy in the time of transmitting; One of and receive only as far as possible the echo of detection direction in the time receiving, orientation and the elevation angle of telling target simultaneously, or the two.In orientation, the elevation angle and the distance of radargrammetry target location, the measurement at orientation and the elevation angle is directly relevant with the performance of antenna.Therefore, antenna performance is compared to other electronic equipments for radar equipment: as communication facilities etc., even more important.
At present, general Mini-type meteorological radar antenna rotation angle sensor is photoelectric sensor, and precision is not high, and radar telemetry is accurate not, and error is larger.In the time implementing artificial rainfall eliminating hail operation, poor effect is often inaccurate closely related with radar data.
Summary of the invention
