Embodiment approach

[0099] As an optional implementation manner, the second device includes:

[0100] target or reflective equipment;

[0101] Wherein, the reflection device has the capability of reflecting signals and the capability of receiving signals.

[0102] The above-mentioned target may be an object or object that needs to be perceived, such as a person, a vehicle and other objects.

[0103] The above-mentioned reflecting device may be an electronic device capable of reflecting signals and receiving signals, such as electronic devices such as large-scale antenna arrays or smart metasurfaces.

[0104] As an optional embodiment, the method further includes:

[0105] The first device sends configuration information to the second device, where the configuration information includes at least one of the following:

[0106] The sending resource location of the sensing signal, the waveform information of the sensing signal, the configuration information of the second device, and the configurat...

Embodiment

[0150] This embodiment may include the following steps:

[0151] Step 1. The first device sends configuration information of the sensing signal to the second device, including at least one of time-frequency resource location, angle of departure (AoD), waveform and other information.

[0152] Step 2: Before sending the sensing signal, the first device uses beamforming technology to align the minimum power direction of the transmitted signal to the second device, such as the smallest direction in the directional diagram, to the second device.

[0153] For example, the first device can switch the beam direction over time, and the time granularity of the baseband digital beamforming of the first device is nanoseconds or lower. The direction of the beamforming. like Figure 4 As shown, at the beginning, the first device is using the beam direction shown in 401 to serve the terminal, and transmits a communication signal with the terminal, for example, the duration is 0-1us (=1000n...

Abstract

Provided are a signal transmission method, a target sensing method, a device and a storage medium, the method comprising: a first device switching a main lobe direction of a transmitted beam from a first direction to a second direction, and sending a sensing signal, the second direction being a direction in which the main lobe direction of the transmitted beam aligns to the second device, and the second direction being a direction in which the main lobe direction of the transmitted beam aligns to the second device; the first direction is different from the second direction; and after the sensing signal is sent, the first device switches the main lobe direction of the transmitting beam from the second direction to the first direction or a third direction, and the third direction is different from the second direction. The embodiment of the invention can avoid increasing the equipment size.

Description

technical field [0001] The present invention relates to the field of communication technology and radar, and in particular, to a signal transmission method, a target perception method, a device and a storage medium. Background technique [0002] With the development of communication and radar technology, there are more and more applications for sensing targets through signals sent by devices, such as millimeter-wave synthetic aperture radar (SAR, Synthetic Aperture Radar, SAR) imaging technology. However, currently, the sensing signal is transmitted mainly by improving the isolation degree of the transceiver antenna of the sensing signal transmission device, and increasing the isolation degree of the transceiver antenna often leads to an increase in the size of the device. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a signal sending method, a target sensing method, a device, and a storage medium, so as to solve the problem that the size o...
