According to an embodiment of the application, a method of adjusting an output power of a microwave radar apparatus is provided.
Fig. 1 is a flow chart of a method of adjusting output power of a microwave radar apparatus according to an embodiment of the application. As shown in fig. 1, the method comprises the steps of:

In step S102, the microwave radar apparatus receives a second radio wave that is returned, wherein the second radio wave is a wave that is reflected by the first radio wave via the object of the specific space.
Specifically, after the microwave radar device transmits the radio wave, the microwave radar device reflects the radio wave to the microwave radar device when encountering a factor to be detected, and an antenna of the microwave radar device receives the reflected radio wave, namely, the second radio wave.
Step S103, based on the intensity of the second radio wave, the output power of the microwave radar apparatus is adjusted.

Specifically, in the prior art, when the microwave radar device is used for measurement, radio waves are often transmitted at a certain fixed power, output power cannot be adaptively adjusted according to the range size of a space to be detected, or the attenuation degree of the radio waves according to the environment where the microwave radar device is located, which results in waste of device output power and inaccurate data measurement, wherein the factors to be detected include the size of the space to be detected (specific space), the microwave radar device can determine the size of the space to be detected through the difference between a second radio wave reflected by a shielding object (wall) of the space to be detected and the transmitted radio wave, and the output power of the microwave radar device is adjusted to be output power matched with the size of the space to be detected based on the size of the space to be detected.

Conversely, if the determined space size is less than the space size threshold, the output power of the microwave radar apparatus needs to be reduced. The output power of the microwave radar equipment is adjusted by determining the comparison between the size of the specific space and the size threshold of the space, so that the technical effect of not wasting the output power under the condition of accurate measurement is realized. The above is a method for adaptively adjusting power of a microwave radar device in a first hierarchy.
Optionally, adjusting the output power of the microwave radar apparatus based on the intensity of the second radio wave comprises: determining a property of the target obstacle within the specific space based on the intensity of the second radio wave; determining a degree of attenuation of the first radio wave based on an attribute of a target obstacle within the specific space; the output power of the microwave radar apparatus is adjusted according to the degree of attenuation of the first radio wave.
Specifically, during measurement, the existing obstacle is also one of the measurement factors, the attenuation degrees of different objects to radio waves are different, if a target obstacle with a large attenuation degree to the radio waves exists in a specific space, the output power of the microwave radar device needs to be adjusted to be high, and if a target obstacle with a relatively small attenuation degree to the radio waves exists in the specific space, the output power of the microwave radar device needs to be adjusted to be low, so that the accuracy of measurement is ensured under the conditions that the output power is not wasted and the loss of the microwave radar device is reduced.
Optionally, with the above description, after the specific space size is determined, the output power of the microwave radar device is adjusted, and after the first-level adaptive power adjustment of the microwave radar device is completed, the second-level adaptive power adjustment of the microwave radar device is completed through the attenuation degree of the target obstacle to the microwave radar.

Specifically, adjusting the output power of the microwave radar is achieved by adjusting an antenna array of the microwave radar, for example: and antenna arrays corresponding to the to-be-detected space with the areas of 3 × 3, 4 × 4 and 1 × 1 are arranged in the microwave radar antenna array group. When the antenna array corresponding to the area 4 x 4 is used in the area 1 x 1, the energy consumption is too large, and the power is wasted, so that the antenna array corresponding to the area 4 x 4 is modified into the antenna array corresponding to the area 1 x 1 according to the detection of the size of the space to be detected, and the adjustment of the output power of the microwave radar equipment is realized by adjusting the antenna array.
Optionally, adjusting the antenna array of the microwave radar device to achieve a more accurate measurement further includes: when measuring a person or an object in a moving state, firstly, the microwave radar device transmits radio waves to the person or the object in the moving state, determines whether the person or the object in the moving state has contents to be detected, for example, whether a mobile phone is held in a human hand or not, if the mobile phone is the contents to be detected, the person in the moving state is the contents to be measured, and according to the moving states of the person and the object, the microwave radar device adjusts the antenna array in real time to ensure that the path of the radio waves transmitted by the adjusted antenna array is consistent with the moving track of the person or the object in the moving state, so that the measuring contents in the moving state can be measured.
