Problems solved by technology

However, at present, foreign anti-collision radars have not yet fully developed and matured, and radars with waveguide structures still dominate, with the disadvantages of poor consistency and difficulty in mass production
Domestic research on automotive radar is in its infancy, and there is no corresponding product on the market

Embodiment Construction

[0028] The anti-collision radar system provided by the present invention has its basic working principle as figure 1 As shown, the linear modulation unit 6 generates a triangular wave with adjustable amplitude, offset and frequency, which is input to the voltage-controlled oscillator 23 in the transceiver assembly 2, so that it generates a high-frequency signal whose frequency changes according to the rule of the triangular wave, and passes through the coupler 22. The circulator 21 and the antenna 1 transmit, meet the target and return, and then receive by the antenna. After passing through the circulator 21, a part of the local oscillator signal coupled to the coupler 22 is mixed by the mixer 24, and the frequency is mixed. The final signal enters the signal processing system 4 to detect the distance of the detection target through the middle amplifier 3, and judges whether it is less than the safety threshold, and then sends it to the alarm and display device 5 for display a...

Abstract

The invention refers to a kind of full-solid integrated, small-type, millimeter-wave crashworthy radar equipment, and its characterized lies in as follows: made up of the antenna, the send-receive module, the linear-modulation cell, the middle-frequency amplifying system, the signal-process systemand the sound-light display warning device; adopting 24HGz high-frequency carrier wave and the micro-band antenna sending and receiving the small-type plane. The linear-modulation cell produces a tri-angle wave whose breadth, polarization and frequency are adjustable, which is input into the voltage-control oscillator in the send-receive module to produce a high-frequency signal whose frequency varies according to the tri-angle law and which is sent out through the coupler.

Description

technical field [0001] The invention relates to a millimeter-wave automobile anti-collision radar device, which mainly solves the technical problem of anti-rear collision during automobile driving. The invention belongs to the technical field of automobile active protection. Background technique [0002] People pay more and more attention to improving the safety of automobiles, and the anti-collision system of automobiles is very important to improve the safety of automobiles. In traffic accident statistics, about 85% of car rear-end collisions are due to driver's negligence and cars following too closely. In order to reduce automobile collisions and the casualties and property losses caused by automobile collisions, many technologies are currently used in the safe driving of automobiles, for example, enhancing the structure of automobiles, installing driving seat belts, and increasing safety airbags, etc., but these passive methods only solve the problem. The protection p...
