One, technical field
The invention belongs to radio monitoring and direction-finding field, make full use of many rotors (multiaxis) Flight Vehicle Structure feature, direction-finder antenna be arranged on horn, composition direction estimation antenna array, realizes the DF and location of radio signal.
Two, background technology
Along with developing rapidly of China's urban construction and increasing of all kinds of radio facility, normal communication also increases increasingly by the event of radio interference.Radiowave when ground propagation, can because the refraction of all media, reflection and become disorderly and unsystematic; And when aloft propagating, almost do not reflect, there is through property.This feature make to monitor in the air the position of interference source that obtains and direction be almost the most truly, information the most accurately.In addition, the aircraft speed implementing aerial monitoring is very fast, and can be flown to rapidly another point by a point, carry out grade separation multipoint positioning, therefore, the position of interference source accuracy rate obtained is very high.
The direction finding of on-air radio pyroelectric monitor supplements as the one of traditional monitoring pattern, existing monitoring net can be formed the multi-function modern three-dimensional monitoring nets such as Long-distance Control, associating direction finding, emphasis monitoring, can realize covering institute's administrative area full frequency band, full-service, all the period of time, omnibearing monitoring, thus General Promotion technology management level.
1. explanation of nouns
1). radio direction finding
According to character and the propagation characteristic of radiowave, use specialized instrument and equipment, measure the process of radio arrival bearing.
2). channels watcher
Measure the specialized instrument and equipment of radiowave arrival bearing.Generally include four parts: direction-finder antenna, Input matching crosspoint, receiver, direction information processes and displays (instruction) unit.
3). radio monitoring
For obtaining frequency spectrum, frequency, signal information or being acquisition radio intelligence information in military struggle in radio spectrum management, and the technological means implemented.Which includes the sport technique segments such as monitoring, direction finding, identification, building database.
4). wireless monitoring
For obtaining radio target frequency bands signal, the relevant information of echo signal, the technological means such as the reception taked, monitoring, identification, analysis, record.
5) many rotors (multiaxis) aircraft
Multi-rotor aerocraft is also Multi-axis aircraft, by the flying platform organized power system more and form, generally common are four rotors, six rotors, eight rotors ... 18 rotors, even more rotor compositions.Electronic multi-rotor aerocraft drives screw propeller to form single group rotor power system, by inertial navigation system, flight control system, navigationsystem, electronic governor composition control drive part by brushless motor.Aircraft can carry the lift-offs such as imaging equipment, Communication Equipment, collection equipment, special equipment as flight carrier, can reach the height (0-500 rice) of traditional approach out of reach.
Multi-rotor aerocraft is different from the feature of other aircraft:
A) multi-rotor aerocraft has obvious advantage with the structure of its uniqueness with succinct system architecture compared with conventional aircraft.
B) move aircraft using Hi cell as energy with oil compared with noise lower, low-latitude flying can be realized and not easily discover.
C) vertical takeoff and landing can just can stabilized flight at comparatively narrow space, and determines to have not by the advantage that place limits compared with rotor aircraft.
D) (only motor bearings the is mechanical part) maintenance compared with conventional helicopters (having more complicated mechanical part and drive mechanism) of simple mechanical part composition is quite simple.
E) clear superiority that volume is little, lightweight, load-carrying is greatly multi-rotor aerocraft, by FHP-Z617, aircraft deadweight 2kg, can carry and comprise the weight of battery pack up to 4kg, load-carrying ability is 2 times of own wt.And development size is less than a sq m, the portable transportation case of 70*65*35 after folding, easily can be received into together with accessory device.
F) complete machine all-electronin increases steady, simple to operate.Autonomous navigation can realize full automaticity flight.The power system of excellent performance provides the flight attitude of maneuverability, and wind loading rating is strong.
Many rotor flyings system can be widely used in agriculture low-to-medium altitude and sow seeds, sprays insecticide, the supervision of security monitoring, forest extinguishing, the condition of a disaster, emergency communication, electric power application, marine applications, weather monitoring, aerial survey of taking photo by plane, also will be developed further to the application of more than 30 the industry aspects such as aerial exploration, noiseless investigation, border patrol, nuclear radiation detection, mineral exploration aviation, traffic patrolling in addition.
