Abstract
The invention relates to a wearable radar alarm device resisting sneak attack, and the device employs an integrated radio frequency front end. The device transmits a continuous wave signal directionally within a certain beam width. Because of the Doppler effect, the device judges the positive/negative property of frequency change and the range of the difference through signal processing after frequency mixing at the radio frequency front end when the frequency of echo, generated when an electromagnetic wave meets with a target, changes, thereby judging whether the target is approaching or not. The device generates sound or gives a vibration alarm if the target is approaching, so as to remind an equipment carrier of increasing attention. Because the device employs K-band microwave, the device is not liable to be affected by the climate of the surroundings in an action range. Because the device employs the integrated microwave front end and a rechargeable battery for power supply, the size of the device is very small, and the device is good in wearable and use performances.

The wearable anti-raid alarm device external structure of Fig. 2: (a) front view; (b) side view; (c) vertical view
Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
Adopt the radio-frequency front-end of integration, continuous wave signal is launched at certain beam angle interior orientation, due to Doppler effect, the change of the echo occurrence frequency produced after electromagnetic wave runs into target, judge the scope of the positive/negative and difference of frequency change through signal transacting after radio-frequency front-end mixing, thus differentiate whether target is being done near motion, if then sound in real time or vibrating alert, prompt facility carrier improves notice.Owing to have employed K-band microwave, in reach, be not vulnerable to the impact of ambient climate environment; Owing to adopting integrated microwave front end and rechargeable battery to power, make equipment volume very little, possess good wearable property and usability.
This Portable alarming device mainly comprises rechargeable battery, the integrated front end of radio frequency, data processing unit, sound/vibration production part and shell, and composition as illustrated in fig. 1 and 2.Wherein the integrated front end of radio frequency comprises micro-band plate aerial and microwave transmitting and receiving assembly, realizes the function of continuous-wave radiation microwave in certain beam angle; The change that data processing unit mainly completes transmitting-receiving microwave signal frequency in certain limit differentiates, and sends trigger pip to sound and vibration production part down imposing a condition;
The present invention adopts and is integrated with dull and stereotyped microstrip antenna, transmitting-receiving subassembly, microwave signal produce and the integrated radio-frequency front end of mixing, for generation of, launch, receive, the microwave signal of mixing K-band.The microwave of alarm device directional transmissions runs into moving target and produces echo in reach, after echoed signal and the mixing that transmits, judges through data processing unit.When target is done away from motion, not toggle sound and vibration component; When target is done near motion, toggle sound and vibrating device parts, carry out alarm, reminds wearer to note.Alarm device in the present invention adopts chargeable lithium cell to power, and is that equipment has reusable ability.
In order to microwave transmission, front panel adopts has comparatively low-k (ε
r≤ 2.5) nonmetallic materials; Simultaneously in order to reduce the radiation of microwave to personnel, housing (except forward sight panel) employs the light-weight metal (as aluminium alloy) with better effectiveness; Back side of shell leaves charging hole and is provided with and buckles, and can hang on the waist of user; Top is provided with by compressing switch, and realizes the switching of facility switching state.
The course of work is as follows: when facility switching is placed in " ON " place, and rechargeable battery starts power supply, and system is in running order.The continuous wave microwave signal of certain beam angle is launched in the integrated front end of radio frequency to specific region, when running into the moving target in reach when microwave signal, produce the echo with different frequency; Echoed signal through radio-frequency front-end receive amplify and with the mixing that transmits after export data processing unit to; The frequency-splitting (echoed signal and the difference on the frequency that transmit) of data processing unit to mixed frequency signal carries out analyzing and processing, if difference on the frequency is negative value, when target is done away from motion, not toggle sound and vibration component, if difference on the frequency be on the occasion of, further its frequency-splitting is judged: when judging that difference on the frequency meets (10 hertz ~ 1 KHz) between setting district, send signal toggle sound and vibrating mass; After sound and vibrating mass receive trigger pip, produce obvious sound and alarm is carried out in vibration, the wearer of alert device improve notice and the inspection carrying out vision dead zone to avoid the generation of raid time.
