With further reference to fig. 4 of the drawings accompanying the present description, a further variant of the variant described above corresponding to fig. 3A and 3B is illustrated, in this variant embodiment of the invention, each of said radiating elements 21 is fed to said first staggered excitation output 111 via a respective feeder line, and to said second staggered excitation output 112 via a respective feeder line, such that the staggered-time emission of the first probe beam and the second probe beam is formed from the same radiation unit 20 based on the staggered-time output of the excitation signal by the excitation source 10 at the first staggered-time excitation output 111 and the second staggered-time excitation output 112, further, compared with the above modified embodiment corresponding to fig. 3A and 3B, the staggered-time scanning detection of the first detection area 301 and the second detection area 302 is realized by using a smaller volume of the staggered-time microwave detection device.

With further reference to fig. 5 of the drawings accompanying the present application, a further variant of the above variant of fig. 4 is illustrated, in which the excitation source 10 has three of the time-staggered excitation outputs 11, i.e. the excitation source 10 further has a third time-staggered excitation output 113, wherein each of the radiating elements 21 is connected to the third time-staggered excitation output 113 by a corresponding feed line feed, so that the time-staggered emission of the first detection beam, the second detection beam and a third detection beam is formed from the same radiating element 20 based on the excitation source 10 being fed by the first time-staggered excitation output 111, the second time-staggered excitation output 112 and the third time-staggered excitation output 113 to the excitation signal, thereby realizing the time-staggered emission of the first detection area 301, the second detection area 302 and a third detection area 303 Time-division scanning detection.

It should be noted that the respective probe beams are kept staggered in time and correspond in number to the number of said staggered excitation outputs 11, in other examples of the mistimed microwave detection device of the present invention, the number of the mistimed excitation outputs 11 of the excitation source 10 is not limited to 2 or 3, for example, the number of time-staggered excitation outputs 11 of the excitation source 10 may be 4, 5, 6, 7, 8, 9, 10, 11, 12 … …, as can be seen from the above description of the embodiments corresponding to fig. 1 to 5, the number of the radiation units 20 is at least one and is not limited to be equal to the number of the timing-staggered excitation output terminals 11, and the number of the radiation elements 21 of each radiation unit 20 is not limited to be the same, the number of corresponding total radiating elements 21 is at least two and is not limited by the number of said time-staggered excitation output terminals 11.

It should be noted that the timing sequence of the excitation signals outputted by the excitation source 10 at each timing excitation output 11 can be controlled by the excitation source 10 to form a timing emission sequence of the corresponding probe beam to control the scanning sequence of the corresponding probe space.

Preferably, the excitation source 10 is capable of outputting the excitation signal at different time intervals according to a fixed sequence through each of the time-staggered excitation output ends 11, so that the corresponding radiation elements 21 are excited, and thus the time-staggered microwave detection device can realize scanning detection of the corresponding detection space according to the fixed scanning sequence. For example, in the specific examples of the staggered-time microwave detection device shown in fig. 1 to 3B, first, the excitation source 10 outputs the excitation signal to the first radiation unit 201 through the first staggered-time excitation output end 111 to allow the first radiation unit 201 to be in an operating state; secondly, after the excitation source 10 stops outputting the excitation signal to the first radiation unit 201 through the first staggered excitation output end 111 and makes the first radiation unit 201 in the non-operating state, the excitation source 10 outputs the excitation signal to the second radiation unit 202 through the second staggered excitation output end 112 and allows the second radiation unit 202 to be in the operating state; the staggered-time microwave detection device can realize scanning detection of the corresponding detection space by enabling the first radiation unit 201 and the second radiation unit 202 to be in a working state according to sequential staggered-time cycle.

It should be noted that, in a specific example of the staggered microwave detecting device of the present invention, the excitation source 10 outputs the excitation signal at the staggered excitation output 11 after stopping at one of the staggered excitation output 11 for a period of time, and then outputs the excitation signal at the other staggered excitation output 11. In another specific example of the staggered microwave detecting device of the present invention, the excitation source 10 outputs the excitation signal at another staggered excitation output 11 immediately after stopping outputting the excitation signal at one staggered excitation output 11, that is, the staggered microwave detecting device always allows only one staggered excitation output 11 to be in a state of outputting the excitation signal.

Further, the output duration of the excitation signal at each of the staggered-time excitation output terminals 11 of the excitation source 10 can be controlled by the excitation source 10 separately, including but not limited to fixed duration control based on program setting and feedback type duration control according to the detection result, so as to form separate control of the staggered-time emission duration of each of the detection beams to control the scanning duration of each of the detection regions.

In particular, the duty cycle of the excitation signal outputted by the excitation source 10 at each time-staggered excitation output end 11 at a time-staggered time can be controlled by the excitation source 10 respectively, so as to form the control of the gain of each detection beam respectively and form the definition of the detection range corresponding to each detection beam, thereby being beneficial to improving the applicability and the anti-interference performance of the time-staggered microwave detection apparatus.

It will be appreciated that the time-staggered microwave detection device has a plurality of detection modes and can be switched between the plurality of detection modes based on the output sequence, the output duration and the duty cycle control of the output excitation signal of the excitation source 10 to each of the time-staggered excitation output terminals 11.

For example, in the moving detection mode, referring to fig. 6A to 6C, the output duration of the excitation signal corresponding to the time-staggered excitation output terminal 11 is short, for example, the output duration of the excitation signal corresponding to the time-staggered excitation output terminal 11 is 5 seconds, and based on the control of the excitation source 10 on the corresponding output sequence of each time-staggered excitation output terminal 11, the time-staggered microwave detection apparatus allows fast scanning of the indoor environment without changing its form, for example, without moving or rotating, so that the time-staggered microwave detection apparatus can improve detection efficiency, reduce the requirement for the installation environment, and reduce power consumption. For example, in the time-staggered microwave detection apparatus of the present invention, the time-staggered microwave detection apparatus includes n radiation units 20, where n is a natural number greater than or equal to 2, where each radiation unit 20 is only electrically connected to one time-staggered excitation output terminal 11, the scanning cycle time of the time-staggered microwave detection apparatus is T, the duration of the detection beam emitted by each radiation unit 20 is T/n, or the duty cycle of each radiation unit 20 is 100/n%. The human body moving in the indoor environment can be detected by the corresponding radiation units 20, and the moving track and the moving law of the human body in the indoor environment can be determined through the detection result and the law analysis of each radiation unit 20.
