Further, different virtual arrays can be obtained based on different working states of the wireless transceiver 40, and the different virtual arrays are synthesized to obtain a synthesized virtual array, which may refer to the related contents of the wireless transceiver 30 in the specific process, which is not described herein again.

A control method provided in the embodiment of the present application is specifically described below with reference to fig. 10.

Specifically, the method may be applied to the above radio transceiver device, as shown in fig. 10, where the control method includes the following steps:

s101, controlling a first switch to conduct a first transmitting antenna and a first transmitting channel in a first time period, and transmitting a radio frequency signal through the first transmitting antenna.

In one implementation, the wireless receiving device may receive a user operation, and in response to the user operation, the wireless receiving device controls the first switch to conduct the first transmitting antenna and the first transmitting channel, and transmits the radio frequency signal through the first transmitting antenna.

Taking the radio transceiver 30 as an example, the transmitting antennas T1 and T1-in the radio transceiver 30 are used for transmitting the second rf signal of the second transmitting channel, T1 and T1-share the second transmitting channel, and T1-are connected to the second transmitting channel through the switch D. Specifically, the wireless transceiver 30 may control the switch D to be in the state (1) in the first time period, at this time, the transmitting antenna T1 is conducted with the second transmitting channel, and the wireless transceiver 30 transmits the second radio frequency signal of the second transmitting channel through the transmitting antenna T1. At this time, the transmitting antenna of the transceiver 30 includes an antenna T0 and an antenna T1, and further, the transceiver may further control the antenna T0 to transmit the first rf signal of the first transmitting channel in a first period, and control the antenna T1 to transmit the second rf signal of the second transmitting channel in a second period, where the waveform of the signal transmitted by the transceiver in the first time period may be as shown in (a) in fig. 7, a first waveform from left to right may represent the first rf signal of the first transmitting channel transmitted by the antenna T0 in the first period, and a second waveform may represent the second rf signal of the second transmitting channel transmitted by the antenna T1 in the second period.

In some embodiments, the transceiver may receive a first echo signal of the rf signal transmitted by the first transmitting antenna through the first receiving antenna array.

In other embodiments, the wireless transceiver first determines the receiving array, and then receives a first echo signal of the rf signal transmitted by the first transmitting antenna through the determined receiving array.

For example, the radio device includes a second switch, a first receiving array, and a second receiving array, and the radio device may first control the first switch to determine the first receiving array as the receiving array in the first time period. Taking the wireless transceiver 30 as an example, referring to fig. 3, the wireless transceiver 30 can control the switch a, the switch B, and the switch C to be in the state (1) in the first cycle time, and at this time, the first receiving arrays are R0, R1, R2, and R3. At this time, the operation state of the radio transceiver 30 is as shown in fig. 4A, and the virtual array corresponding to the radio transceiver 30 is as shown in fig. 4B. As shown in fig. 7, the wireless transceiver 30 may receive the first echo signals H-R0, H-R1, H-R2 and H-R3 by receiving the echo signals from the antennas R0, R1, R2 and R3.

And S103, controlling the first switch to conduct the second transmitting antenna and the transmitting channel in a second time period, and transmitting the radio-frequency signal through the second transmitting antenna, wherein the second time period is a time period after the first time period.

Specifically, the wireless transceiver may switch the first switch after the first time period is over, control to switch on the second transmitting antenna and the transmitting channel, and transmit the radio frequency signal through the second transmitting antenna.

Optionally, a time difference between the first time period and the second time period is not greater than a preset time period. As can be understood, in some scenarios, the detection target may be changed due to the too long time difference between the first time period and the second time period, and the echo signal of the radio frequency signal transmitted by the different transmitting antenna for the target cannot be obtained.

Taking the wireless transceiver 30 as an example, specifically, the wireless transceiver 30 may control the switch D to be in the state (2) in the second cycle time, at this time, the transmitting antenna T1-is conducted with the second transmitting channel, and the wireless transceiver 30 transmits the second radio frequency signal of the second transmitting channel through the transmitting antenna T1-. At this time, the transmitting antenna of the wireless transceiver 30 includes an antenna T0 and an antenna T1 —, and further, the wireless transceiver may further control the antenna T0 to transmit the first radio frequency signal of the first transmitting channel in a first umbrella period, and control the antenna T1 to transmit the second radio frequency signal of the second transmitting channel in a fourth period, the waveform of the signal transmitted by the wireless transceiver in the second time period may be as shown in (a) in fig. 7, a third waveform from left to right may represent the first radio frequency signal of the first transmitting channel transmitted by the antenna T0 in the third period, and a fourth waveform may represent the second radio frequency signal of the second transmitting channel transmitted by the antenna T1 in the fourth period.

And S104, receiving a second echo signal of the radio-frequency signal transmitted by the second transmitting antenna through the first receiving antenna array.

In some embodiments, the wireless transceiver may receive a second echo signal of the radio frequency signal transmitted by the second transmitting antenna through the first receiving antenna array.

In other embodiments, the transceiver includes a first receive array and a second receive array, and the transceiver may first control the first switch to determine the receive array during the first time period. Taking the wireless transceiver 30 as an example, the wireless transceiver can control the switch a, the switch B, and the switch C to be in the state (2) in the first cycle time, and at this time, the first receiving arrays are R0, R1-, R2-, and R3-. At this time, the operation state of the radio transceiver 30 is as shown in fig. 5A, and the virtual array corresponding to the radio transceiver 30 is as shown in fig. 5B.

And S105, splicing the first echo signal and the second echo signal based on the time sequence to obtain a synthesized signal.

Specifically, the wireless transceiver may splice the first echo signal and the second echo signal according to a sequence of the received echo signals to obtain a composite signal. It can be understood that, in the embodiment of the present application, under the condition that the channel resource is limited, one transmission channel can be shared by at least two transmission antennas, so as to obtain a composite signal with a larger data volume, and further, the wireless transceiver can determine the position, the angle, and the like of the target through the composite signal.

Taking the radio transceiver 30 as an example, see (B) in fig. 7, and (B) in fig. 7 exemplarily shows a splicing process in which one receiving channel receives echo signals in two operating states of the radio transceiver 30. And will not be described in detail herein.

The Runtime (Runtime) includes a core library and a virtual machine. Runtime is responsible for scheduling and management of the system.

The core library comprises two parts: one part is the function that the programming language (e.g. java language) needs to call, and the other part is the core library of the system.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes programming files (e.g., jave files) of the application layer and the application framework layer as binary files. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.
