A Method of Acquisition and Processing of Calibration Flight Data of Ultrashort Wave Orientation Station

Abstract

The invention provides an ultra-shortwave direction-finding station flight correction data acquisition and processing method. The method comprises the steps that (1) before data information acquiring, video, audio and differential GPS timing are carried out; (2) direction-finding station audio and video information and airborne differential GPS information are acquired; (3) the audio information is analyzed and processed to form a data sequence under a time identity, wherein the data sequence comprises communication frequency and communication duration; (4) video information image analysis, segmentation, contrast and recognition are carried out to form an azimuth data set under the time identity; (5) azimuth error processing under specific height and distance after aligned screening is carried out on a video after timing and the data set after GPS resolving according to a step audio data sequence, and error comparative analysis is carried out on the calculated data and direction-finding station correction technical parameter requirement in military standards; and (6) device calibration commissioning is carried out according to a error value for disqualification, and then flight correction verifying is carried out. According to the processing method provided by the invention, the directional precision of a device can be improved; the number of times of flight correction is reduced; in a data acquisition process, the operation state of the device is not affected; and a solid technical support is provided for flight.

Description
