Background technique

In recent years, radar has been widely used in various fields. In the automotive field, radar serves as a complementary technology for cameras and lasers. In the field of Internet of Things (IoT), radar can be used for sleep detection in smart homes, personnel density detection in smart offices, fatigue driving detection in smart cars, and detection of breathing and heart rate during sleep.

Embodiments of the present application provide radar control methods and devices, which can improve the adaptability of radar. In order to achieve the above objectives, the embodiments of this application adopt the following technical solutions:

In a first aspect, embodiments of the present application provide a radar control method, which method includes: first acquiring target information of a radar, and then adjusting target parameters of the radar according to the target information. Wherein, the target information includes at least one of target distance, target radial velocity, target angular interval or target angular velocity, and the target distance is the distance between the two closest target objects among multiple target objects, so The target radial speed is the radial speed of the target object with the fastest radial speed among the plurality of target objects, and the target angular interval is the distance between the two target objects with the smallest angular interval among the plurality of target objects. Angular interval, the target angular velocity is the angular velocity of the target object with the fastest angular velocity among the multiple target objects, and the target object is the measured object located within the radar detection range. The target parameter includes at least one of bandwidth or number of transmit and receive (transmit receive, TRX) channels.

Compared with existing radars that use fixed bandwidth and TRX channel number, the radar control method provided by the embodiment of the present application can adjust the radar according to the distance, radial velocity, angular interval, angular velocity and other data of the measured object within the radar detection range. bandwidth and the number of transceiver channels, thereby increasing the adaptability of the radar.

For example, the radar control method provided by the embodiment of the present application can reduce the bandwidth and/or the number of TRX channels of the radar in scenarios with low resolution requirements (such as detecting respiratory heart rate in sleep state, detecting pulse waves on the skin surface) to reduce unnecessary Necessary energy consumption and reduction of interference to other communication systems and radar systems in adjacent frequency bands.

For another example, the radar control method provided by the embodiments of the present application can increase the bandwidth and/or the number of TRX channels of the radar in scenarios with high resolution requirements (such as distinguishing multiple targets in close proximity, detecting fast-moving or violently moving targets), To improve the range/angle resolution performance of the radar system.

In a possible implementation, the target distance may be the radial distance between two target objects with the closest radial distance among the plurality of target objects.

The above-mentioned measured objects may be all or part of the objects within the radar detection range. For example, it can be some objects customized by the user (for example, it can be people within the radar detection range. For example, it can be still objects such as tables and chairs within the radar detection range.)

The above-mentioned measured objects include but are not limited to people, furniture, electronic equipment, and other objects in homes/offices/shopping malls/cars.

In a possible implementation, the target information may include the target distance. The target parameters may include bandwidth, and adjusting the target parameters of the radar according to the target information may include: adjusting the bandwidth of the radar according to the target distance.

For example, when the target distance is less than the first distance threshold, the bandwidth of the radar may be increased.

In this case, the number of TRX channels of the radar can be increased to improve the angle of the radar system. resolution performance.

As another example, when the target angular interval is greater than the second angular interval threshold, the number of TRX channels of the radar can be reduced.

It should be noted that if the target angular interval is greater than the second angular interval threshold, it means that the angular interval between two measured objects within the radar detection range is large. In this case, the number of TRX channels of the radar can be reduced to reduce unnecessary energy. Consumption and reduce interference to other communication systems and radar systems in adjacent frequency bands.

In a possible implementation, the angular interval between multiple objects within the radar detection range can be first obtained, and then the angular interval between the two target objects with the smallest angular interval among the multiple target objects is determined as the target angular interval. .

At this time, the number of TRX channels of the radar can be increased to improve the angular resolution performance of the radar system.

As another example, when the target angular velocity is less than the second angular velocity threshold, the number of TRX channels of the radar can be reduced.

It should be noted that the target angular velocity is less than the second angular velocity threshold, which means that the angular velocity of the measured objects within the radar detection range is slow.
