Problems solved by technology

This may also be related to the small application range of this technology, and the related group tracking technology cannot be directly applied to high-voltage line types, and the processing effect on high-voltage lines is not ideal.
[0006] Current problems: analysis and detection of high-voltage line position and high-voltage line track processing
Moreover, the drawing of high-voltage lines cannot be interrupted. The lack of intermediate points will inevitably seriously affect the quality of the entire high-voltage line. However, the inevitable shaking of the helicopter during flight and the occlusion of unknown objects will cause individual high-voltage line points to flicker. This also requires us to use the track processing algorithm to compensate for this short-term point loss phenomenon and maintain the complete display of the high-voltage line

Embodiment Construction

[0047] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0048] On-the-spot detection of high-voltage lines in a certain area, the scanning range is -45°~+45° directly in front, within 5km. After a series of processing such as receiving and processing by the receiver, the primary point data is obtained. It contains information such as range, azimuth, elevation, amplitude and Doppler for each point. These points are dealt with as follows:

[0049] Step 1: Process the primary point of the radar echo, and start the track at the high-voltage line point.

[0050]a. According to the magnitude of the primary point, remove the sidelobe points at the same distance; first, find the point with the largest magnitude among the track points at the same distance; then, compare this point with other points at the same distance and different azimuths Amplitude; when the ratio of the two amplitudes is greater than 10dB, we think that...

Abstract

The invention relates to a flight track processing method for chain points and a whole chain of high voltage wires. In combination of multiple characteristics of high voltage wire targets and through data analysis and processing, the problems of positioning and detecting the high voltage wires are effectively solved; by the method, references can be provided for crash prevention and navigation of a low-altitude aircraft in poor sight line environment and risks of low-altitude flight are effectively reduced; the difficulty of analyzing and detecting the positions of the high voltage wires is overcome; the various high voltage wires are taken as a whole, a special flight track processing algorithm is adopted; in combination with a flight track processing algorithm on iron tower points, a relationship between the flight tracks and point tracks of the high voltage wires is skillfully processed; the output stability of the flight tracks of the high voltage wires is greatly improved; the output instability caused by platform jitter and point glittering of the high voltage wires are effectively solved; and the flight track processing difficulty of the high voltage wires is effectively solved.

Description

technical field [0001] The invention belongs to the field of high-voltage line detection data processing, and relates to a high-voltage line chain point and the entire chain track processing that can analyze the position of the high-voltage line and realize the stable output of the high-voltage line track by analyzing and processing the radar echo data of the high-voltage line method. Background technique [0002] At present, there are not many researches on high-voltage line data processing technology. Most of them are research on high-voltage line detection itself. Due to the characteristics of high-voltage line targets themselves, the track processing of group target tracking is similar to the processing of high-voltage line track. The following articles indicate this field background technology: [0003] Geng Wendong's "Research on PDA-Based Group Target Merging and Separation Method" published in "Signal and Information Processing" 2007 Radio Engineering. A probabilis...
