As shown in fig. 3 and 4, in the embodiment of the present application, in the case where the rf access port 122 outputs a signal of the first ultra-wideband frequency band or the second ultra-wideband frequency band,

It can be understood that, in the embodiment of the present application, if the rf input/output port 122 outputs a signal of a first ultra-wideband frequency, the second switch 112 needs to implement the third switch 113 to connect with a first ultra-wideband frequency port corresponding to the first ultra-wideband frequency in the second frequency divider 117, so as to enable transmission of the signal, that is, the signal is input from the port, then output from a common port of the second frequency divider 117 to the second ultra-wideband antenna 102, and finally emitted by the ultra-wideband antenna, and correspondingly, if the rf input/output port 122 outputs a signal of a second ultra-wideband frequency, the second switch 112 needs to implement the third switch 113 to connect with a second ultra-wideband frequency port corresponding to the second ultra-wideband frequency in the second frequency divider 117, so as to enable transmission of the signal, that is input from the port, then output from the common port of the second frequency divider 117 to the second ultra-wideband antenna 102, and finally emitted by the ultra-wideband antenna.
Fig. 5 is a schematic diagram illustrating a signal flow provided in the embodiment of the present application. Fig. 6 is a schematic signal flow diagram illustrating a fourth exemplary embodiment of the present disclosure. Specifically, in the embodiment of the present application, as shown in fig. 5 and 6, in the case where the angle measurement function is implemented based on the signal of the first ultra-wideband frequency band,

It can be understood that, in the embodiment of the application, in the case that the angle measurement function is implemented based on the signal of the first ultra-wideband frequency band, in addition to the one path of signal of the first ultra-wideband frequency band, another path of signal of the first ultra-wideband frequency band needs to be acquired, where measurement of different dimensional angles can be implemented according to the signal of the first ultra-wideband frequency band in the signals received by different ultra-wideband antennas connected to the first switch 111. When measuring a first dimension angle, the first switch 111 needs to control the first ultra-wideband antenna 101 to be connected with the first frequency divider 116, when measuring a second dimension angle, the first switch 111 needs to control the third ultra-wideband antenna 103 to be connected with the first frequency divider 116, and in addition, when measuring any dimension angle, the second switch 112 needs to control the connection between the first ultra-wideband frequency band port of the first frequency divider 116 and the radio frequency input port 121, so that a signal of the first ultra-wideband frequency band separated by the first frequency divider 116 is transmitted to the ultra-wideband communication module 12.
