Embodiment 1

[0054] Embodiment 1: Taking the "automatic surveying and mapping mode" task of the spectrum situational awareness surveying and mapping based on the UAV platform as an example, the implementation process (see figure 2 shown) as follows:

[0055] The first step, after completing the pre-start check, select the "automatic surveying and mapping mode", and set the surveying and mapping parameters in the brain module 1-9 as shown in Table 1: the starting position of the measurement area (118.803119, 31.916319), the end position of the measurement area (118.792819, 31.897656), the height is 135m, the surveying and mapping antenna is an ultra-wideband passive omnidirectional antenna (frequency band 20MHz—8GHz), and the surveying and mapping resolution is 10; the brain modules 1-9 independently plan the flight path of the UAV according to the surveying and After the track as Figure 5 shown by the green line.

[0056] The specific implementation process of the brain module 1-9 cont...

Embodiment 2

[0064] Embodiment 2: Taking the "manual surveying and mapping mode" task of spectrum situational awareness surveying and mapping based on the UAV platform as an example, the implementation process (see image 3 shown) as follows:

[0065]The first step, after completing the pre-startup inspection, select "manual surveying and mapping mode", and set the surveying and mapping parameters in the brain module 1-9 as shown in Table 2: the surveying and mapping antenna is an ultra-wideband passive omnidirectional antenna (frequency band is 20MHz—8GHz) , the mapping resolution is 10; the user operates the UAV from the starting point (118.796815, 31.93869) with a height of 120m through the remote control module 1-10, and reaches the end point (118.803681, 31.935922) with a height of 120m, so as to perform the three-dimensional spectrum of the path Situation mapping.

[0066] The specific process of remote control module 1-10 program-controlled UAV flight is as follows: remote control ...

Abstract

The invention discloses a spectrum situation cognition surveying and mapping device and method based on an unmanned aerial vehicle platform. The device comprises an unmanned aerial vehicle platform unit, a frequency spectrum situation acquisition unit, a communication and telemetry integrated transmission unit and a frequency spectrum data cognition unit. The unmanned aerial vehicle platform unitcomprises a GPS receiving module, a flight control module and an image module, and the frequency spectrum situation acquisition unit is composed of an airborne frequency spectrum receiver and an omnidirectional antenna; the remote communication integrated transmission unit is composed of a microcomputer and an airborne data link terminal. The spectrum data cognition unit comprises a ground receiving module, a brain module and a remote control module. The unmanned aerial vehicle platform unit, the frequency spectrum situation acquisition unit and the telemetry and telemetry integrated transmission unit form an aerial unmanned aerial vehicle part of the device, and the frequency spectrum data cognition unit is a ground part of the device. The GPS receiving module, the flight control module,the image module and the spectrum situation acquisition unit are connected with the remote communication integrated transmission unit, and the ground receiving module is connected with the brain module.

Description

Technical field: [0001] The invention relates to unmanned aerial vehicle communication and spectrum awareness surveying and mapping technology, in particular to a spectrum situation awareness surveying and mapping device and method based on an unmanned aerial vehicle platform, which belongs to the field of wireless information transmission. Background technique: [0002] The electromagnetic spectrum has become an indispensable national strategic resource in the information age. With the rapid development of space-ground integrated information network, aviation aircraft and other fields, the electromagnetic space is facing the challenge of the shortage of spectrum resources and the severity of spectrum security extending to the airspace, and the spectrum space is becoming increasingly complex. Traditional spectrum monitoring equipment has been difficult to adapt to the development needs of spectrum measurement extending from time, frequency, and signal domains to air domains,...
