In step 101, a target to be identified using a door access is first acquired, and in the embodiment of the present invention, the target to be identified may be a living body, i.e., a person using the door access, or may not be a living body, i.e., may be a tool for forging a living body using a mask, etc.
In the embodiment of the present invention, there are various methods for acquiring the target to be recognized, for example, determining the target to be recognized using a video monitoring system, determining the target to be recognized using an acoustic scanning system, or detecting the target to be recognized using electromagnetic waves.
For example, in the embodiment of the present invention, millimeter waves can be used to acquire an object to be identified, and the millimeter waves have a wavelength of 1-10 mm and are located in a wavelength range where microwaves and far-infrared waves overlap, so that the present invention has the characteristics of two spectra. Compared with light waves, the millimeter waves are small in attenuation when being transmitted by utilizing an atmospheric window and are slightly influenced by natural light and a thermal radiation source. The millimeter wave has the following advantages:
1. extremely wide bandwidth. Generally, the millimeter wave frequency range is 26.5-300 GHz, and the bandwidth is up to 273.5 GHz. More than 10 times the total bandwidth from dc to microwave;
2. the beam is narrow. The beam of millimeter waves is much narrower than the beam of microwaves for the same antenna size. For example, a 12cm antenna, has a beam width of 18 degrees at 9.4GHz and only 1.8 degrees at 94 GHz. Therefore, small objects which are closer to each other can be distinguished or the details of the objects can be observed more clearly;
