Embodiment Construction

[0028] Theoretical basis and working principle that the inventive method realizes:

[0029] (1) Method

[0030] Refit and fix the timing equipment after GPS timing to the panel of the ultrashort wave directional table, fix the camera on the bracket, adjust the picture so that the heading / azimuth information, timing equipment and vibrator information on the digital display window of the directional table are clearly displayed on the camera on the screen.

[0031] The aircraft flies according to the scheduled route, and the differential GPS system records the flight track information of the aircraft throughout the process, and at the same time collects and records the output data of the ultrashort wave directional station (completed by the camera and recorder equipment); Record the communication data of the station, and obtain the azimuth information in the respective data through calculation and processing; compare the same-named parameters in the two sets of data to obtain th...

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

technical field [0001] The invention relates to a method for collecting and processing flight calibration data of an ultrashort-wave directional station, and belongs to the technical field of data processing. Background technique [0002] The ultrashort wave directional station is the necessary equipment for flight support. During the service period, the ultrashort wave directional station must carry out regular flight inspections to verify whether the directional accuracy, operating distance and coverage of the ultrashort wave directional station meet the service requirements; And the ability to assist in guiding the aircraft to approach and land in an emergency. [0003] The main technical parameters of the ultrashort wave directional station are digital display information. Due to the limitation of the equipment program, the commonly used level conversion data acquisition affects the normal operation of the equipment, and the phenomenon of parameter deviation or abnormal ...
