Problems solved by technology
[0004] The present invention aims at the life detection existing in the prior art, which needs to continuously move the radar life detector, and change the detection azimuth and angle to complete the detection of the entire plane area or room. If the transformation and movement are too large and exceed the coverage of the detection radar beam, There will be missed detection areas, resulting in missed detection of life, making life lose the chance of being discovered and rescued, and thus losing life; if the amount of transformation and movement is too small, it will cause repeated detection, and the number of given life bodies will be too large Due to the actual amount of wrong information, adding unnecessary troubles to follow-up rescue, a method for time-sharing rotary scanning detection of radar life detectors is proposed

The invention discloses a method for time-share rotary scanning detection method for a radar vital sign detector. The method comprises the following steps of: erecting a radar in the middle of a wall according to a position to be detected and a range to be detected; determining a detection region of the radar according to a wave velocity width phi degree of the radar and a range of the detection region; and after all the regions in the detection range are detected, generating a vital sign distribution planar graph of the whole region on a computer. According to the method, the radar vital sign detector is deflected at a fixed angle by adopting a gradual deflection scanning detection mode, so that the detection direction of the detector can be changed, and vital sign distribution in the whole region or a room can be gradually finished without moving the radar detector. Each deflection angle of the radar is equal to the wave velocity width of the radar, so that problems of region leakage, repeated detection, leakage detection and the like can be solved. The method is simple, reliable and favorable for detection; the result is accurate and reliable; the method is convenient; and furthermore, the vital sign distribution planar graph can be generated.
Description
Technical field [0001] The invention belongs to the technical field of radar detection, and in particular relates to a method for time-sharing rotation scanning detection of a radar life body detector. Background technique [0002] In life detection, it is often necessary to monitor and detect whether there is hidden life behind the building. However, conventional radar life detectors can only detect a certain cone area. If you want to complete the detection of the entire plane area or the entire room behind the building, you need to constantly move the radar life detector, change the detection position and angle. Only one detection can complete the detection of the entire flat area or room. [0003] But changing the detection position and angle of the radar life detector is a rigorous scientific issue. If the amount of transformation and movement is too large and exceeds the coverage of the detection radar beam, a missed area will be generated, resulting in missing life, and lif...
