Description
Technical Field
The utility model relates to the technical field of radio monitoring, in particular to radio monitoring direction-finding equipment based on a multi-rotor unmanned aerial vehicle.
Background
The types of radio monitoring direction-finding equipment available in the market at present include fixed type, vehicle-mounted type, portable type, handheld type and the like, but are limited by factors such as positions, quantity, frame height, surrounding environment influence and the like, so that the radio monitoring direction-finding equipment has great limitations on the discovery, accurate direction finding and positioning of a radiation source, and the following specific factors are provided.
Difficulty in detecting coverage: both portable and vehicle-mounted detection equipment are detection facilities deployed on the ground, and a detection antenna is generally elevated by about 2-6 meters, so that the detection coverage range is very small. From the detection practice, the detection of several tens of watts of emitted power radio radiation source finds a distance generally in the range of ten kilometers. If the terrain is complex and there are many obstructions, the detection range will be smaller, even several kilometers. For a battle area with a depth of tens of kilometers, the detection coverage capability of several kilometers will cause many detection blind areas if a large number of detection devices are not deployed. If a large amount of monitoring equipment needs to be deployed, the required guarantees of the number of equipment personnel, data transmission, damage resistance and the like are difficult to meet.
The accurate positioning of the radiation source is difficult: the direction-finding accuracy of the radio direction-finding equipment deployed on the ground is greatly influenced by the occlusion and reflection of terrain and ground objects, so that a large error is generated in the positioning of a radiation source, and the error often exceeds the bottom line of the position of the radiation source judged by the system, so that the positioning data of the radiation source cannot be informed by a target situation system.
The detection efficiency is low: most of the active monitoring and direction-finding equipment is basically the technology of the nineties of the last century, and does not adopt the advanced detection and integration technology. The signal detection discovery and the signal direction finding are two separated functions, and the broadband parallel processing capability is weak, so that the scanning direction finding efficiency is low. In the case of a complex electromagnetic environment, if the detection device does not have a high-speed scanning direction-finding capability, the detection device cannot dynamically grasp the information of the positions, the emission activity conditions and the like of all radiation sources in real time, and cannot detect low-interception probability signals (frequency hopping signals, radar signals, data link signals and the like).
In a word, the radio monitoring direction-finding system applied in a large number at present is limited by the ground deployment mode, and the capability of accurately and quickly acquiring the position of a radiation source is weak. In order to get rid of the ground limitation, the monitoring and direction-finding equipment is lifted to the air for detection, which is the only way to solve the problem.
The lift-off platform is a difficult problem troubling lift-off detection, and platforms such as captive balloons and unmanned aerial vehicles have been considered in the industry, but the platforms are not adopted due to short dead time, poor tactical performance, inconvenience in control, weak survivability and the like.
According to the patent application with the application number of CN201710825341.6, the device includes a supporting seat and an undercarriage connected with the supporting seat, a program control device cabin of a machine body is connected to the undercarriage top end, a radio device cabin is arranged on the upper portion of the program control device cabin, a radio omnidirectional antenna and a GPS antenna are installed on the top of the radio device cabin, a battery pack is installed on the top end of the radio device cabin, the machine body formed by the program control device cabin, the radio device cabin and the battery pack is connected with a plurality of machine arms, a motor is installed at the tail end of each machine arm, and an output shaft of the motor is fixedly connected with a propeller through a fixing knob. Although the device can bring the radio monitoring and direction-finding equipment into the air, the structure of the device is too complex, and the volume and the weight are large, so that the dead time is short, and the practicability is low.
