Description
Technical field
The utility model designs a kind of unmanned plane and keeps away barrier radar installations, a kind of reasonable in design of specific design, 360 degree panoramic scanning radars of the unmanned plane obstacle avoidance based on mirror-reflection.
Background technology
Existing unmanned plane obstacle avoidance, generally adopts vision, ultrasonic wave or laser. Adopt vision scheme when light is darker, to there will be identification to decline, run into and snow, rain, the adverse weathers such as dense fog also can be easy to occur identification error. Adopt the ultrasonic evadible system distance that can detect very short, the demand that can not meet outdoor unmanned plane and keep away barrier. Employing laser is with high costs, and runs into the problem that bad weather still there will be recognition accuracy to decline. Overcome above shortcoming, can penetrate bad weather and adopt millimetre-wave radar to keep away barrier, detection range is long, and cost is low.
Conventional art wants to carry out 360 degree panoramic scannings with radar, has two schemes: 1, and radar self carries out 360 degree scannings; 2, adopt phased-array radar, design multiple antennas and radar transmit-receive module, change and scan by phase place. The first scheme needs complicated motor device, is not suitable for SUAV. First scheme needs multiple radar transmit-receive modules, has increased greatly cost.
Therefore, the necessary a kind of reasonable in design of research and development that designs on the basis of prior art, cost is low, can be applied to 360 degree panoramic scanning radar installations of SUAV obstacle avoidance.
Utility model content
Utility model object: the purpose of this utility model is that cost is low for a kind of reasonable in design is provided, can be applied to 360 of SUAV obstacle avoidance and spend panoramic scanning radar installations.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of unmanned plane based on mirror-reflection is kept away barrier radar, it comprises radar shell, be arranged on millimetre-wave radar front end and the baseband processing circuitry of inside, radar shell bottom side, be arranged on the millimetre-wave radar lens of millimetre-wave radar front end and baseband processing circuitry top, be arranged on the rotation minute surface of millimetre-wave radar lens top, rotation minute surface is connected with motor.
As preferred version, above-described a kind of unmanned plane based on mirror-reflection is kept away barrier radar, 1 or 2, described millimetre-wave radar lens.
As preferred version, above-described a kind of unmanned plane based on mirror-reflection is kept away barrier radar, and described rotation minute surface and horizontal direction are miter angle.
As preferred version, above-described a kind of unmanned plane based on mirror-reflection is kept away barrier radar, described millimetre-wave radar front end and baseband processing circuitry comprise front ends of millimeter waves circuit and antenna, the intermediate frequency filtering amplification module being connected with antenna with front ends of millimeter waves circuit, the analog digital modular converter being connected with intermediate frequency filtering amplification module, the digital signal processing module being connected with analog digital modular converter.
As preferred version, above-described a kind of unmanned plane based on mirror-reflection is kept away barrier radar, and described motor is arranged on the top of radar shell.
The unmanned plane based on mirror-reflection that the utility model provides is kept away barrier radar, and the millimeter wave upwards vertically being sent by millimetre-wave radar front-end circuit driven antenna, after the focusing of millimetre-wave radar lens, incides rotation minute surface. After a mirror-reflection, electromagnetic wave is from becoming vertically upward horizontal direction, and its shooting angle depends on the rotation current position of minute surface. Rotation driven rotary minute surface by motor ceaselessly rotates, thereby the millimeter wave of vertical incidence is become to the millimeter wave of the horizontal aspect of 360 degree transmittings. Meanwhile, the millimeter wave that extraneous barrier reflects, reflects again by rotation minute surface, is received, and process after millimetre-wave radar lens focus by millimetre-wave radar antenna and front-end circuit. So, around unmanned plane, the environment of 360 degree are fabricated out, if run into barrier, can measure the angle of obstacle distance unmanned plane, and position and relative velocity, for unmanned plane provides barrier avoiding function.
Beneficial effect: a kind of unmanned plane based on mirror-reflection that the utility model provides is kept away barrier radar and compared to the prior art had the following advantages:
Novel a kind of unmanned plane based on mirror-reflection that the utility model provides is kept away barrier radar, reasonable in design, and cost is low, can be applicable to SUAV. The utility model utilize millimeter wave wave beam assemble advantage, by relay lens, instead of radar self realize 360 degree detect, thereby can simplify electric machine structure. Than phased-array radar, the utility model only needs a radar transmit-receive module, and cost significantly declines.
The utility model, is not only applicable to the obstacle avoidance system of unmanned plane, and also can be used for robot, dust catcher etc. needs machine to carry out in real time surrounding environment being carried out to 2D, the situation of 3D modeling.
