根据本申请的实施例，提供了一种调整微波雷达设备的输出功率的方法。
图1是根据本申请实施例的一种调整微波雷达设备的输出功率的方法的流程图。如图1所示，该方法包括以下步骤：
步骤S101，微波雷达设备在特定空间内发射第一无线电波。
具体地，通常情况下，微波雷达设备在进行测量时，会设置一个固定的输出功率，微波雷达设备会以这个设定的固定功率发射无线电波进行测量。本申请提供的实施例中，固定输出功率可以不必调整，而就以固定功率发射无线电波即可。
步骤S102，微波雷达设备接收返回的第二无线电波，其中，第二无线电波为第一无线电波经由特定空间的对象反射回来的电波。
具体地，微波雷达设备在发射无线电波后，遇到待检测因素会反射无线电波至微波雷达设备，微波雷达设备的天线接收反射回来的无线电波，即第二无线电波。
步骤S103，基于第二无线电波的强度，调整微波雷达设备的输出功率。
具体地，微波雷达设备通过接受到的反射回来的第二无线电波的强度来判断待检测因素，通过判断出的待检测因素调整输出功率，其中，输出功率与待检测因素相匹配。
可选地，基于第二无线电波的强度，调整微波雷达设备的输出功率包括：基于第二无线电波的强度，确定特定空间的大小；基于特定空间的大小，调整微波雷达设备的输出功率。
具体地，相关技术中，微波雷达设备在测量时，往往以某一个固定的功率发射无线电波，不能根据所测空间的范围大小，或者根据所在环境的对无线电波的衰减程度进行自适应调节输出功率，导致设备输出功率浪费、数据测量不精确，其中，待检测因素中包括待检测空间(特定空间)的大小，微波雷达设备可以通过待检测空间的遮挡物(墙壁)反射回来的第二无线电波与发射出的无线电波的差值确定待检测空间的大小，基于待检测空间的大小调整微波雷达设备的输出功率为与待检测空间大小相匹配的输出功率。
可选地，基于特定空间的大小，调整微波雷达设备的输出功率包括：判断特定空间的大小是否超过空间大小阈值；在特定空间的大小超过空间大小阈值，则调高微波雷达设备的输出功率；在特定空间的大小低于空间大小阈值，则调低微波雷达设备的输出功率。
具体地，根据上述通过特定空间的大小调整微波雷达设备的输出功率包括：通过固定功率设置一个空间大小阈值，其中，空间大小阈值与固定功率相匹配，在通过第二无线电波确定特定空间大小后，将确定后的特定空间与空间大小阈值相比较，如果确定的特定空间大小超过空间大小阈值，则需要将微波雷达设备的输出功率调高。相反地，如果确定的空间大小小于空间大小阈值，则需要将微波雷达设备的输出功率降低。通过确定特定空间的大小与空间大小阈值的比较，来调整微波雷达设备的输出功率，实现了在测量准确的情况下，不浪费输出功率的技术效果。上述内容是微波雷达设备第一层次自适应调节功率的方法。
可选地，基于第二无线电波的强度，调整微波雷达设备的输出功率包括：基于第二无线电波的强度，确定特定空间内的目标障碍物的属性；基于特定空间内的目标障 碍物的属性，确定第一无线电波的衰减程度；根据第一无线电波的衰减程度，调整微波雷达设备的输出功率。
具体地，测量时，存在的障碍物也是测量因素之一，不同的物体对无线电波的衰减程度是不一样的，如果特定空间内存在对无线电波衰减程度大的目标障碍物，则需要将微波雷达设备的输出功率调高，如果特定空间内存在对无线电波衰减程度相对较小的目标障碍物，则需要将微波雷达设备的输出功率调低，以保证在不浪费输出功率、降低微波雷达设备损耗的情况下，确保测量的准确性。
可选地，通过上述描述，在通过确定特定空间大小后，对微波雷达设备的输出功率进行调整，完成微波雷达设备的第一层次自适应调节功率后，再通过目标障碍物对微波雷达的衰减程度完成微波雷达设备的第二次自适应功率调节。
可选地，基于第二无线电波的强度，确定特定空间内的目标障碍物的属性包括：利用第二无线电波描绘目标障碍物的轮廓与确定目标障碍物的材质；根据目标障碍物的轮廓和材质确定目标障碍物的属性。。
具体地，不同的物体对无线电波的衰减程度是不一样的，将反射回来的第二无线电波利用二维图像成像原理描绘障碍物的大致轮廓，并根据反射回来的第二无线电波确定障碍物的材质，基于障碍物的轮廓和材质确定出环境中障碍物体的属性，不同属性的障碍物对无线电波的衰减因子大有不同，根据不同的衰减因子选择合适的输出功率，从而自适应调节微波雷达设备的输出功率。
可选地，在调整微波雷达设备的输出功率之后，该方法还包括：根据功率最优算法对调整后的微波雷达设备的输出功率进行最优输出功率评估，其中，功率最优算法预先存储在微波雷达设备的控制器中；基于评估结果再次调整微波雷达设备的输出功率。
具体地，通过根据特定空间的大小和存在于特定空间内的目标障碍物，微波雷达设备进行了两次输出功率调节，第三步就是在前两步的基础上进行最优输出功率算法评估，对前两个步骤进行更加合理的输出功率调节，完成微波雷达设备最后一次自适应功率调节，其中，功率最优算法是预先存储在微波雷达设备中的，通过功率最优评估得到的结果，再次调整微波雷达设备的输出功率。
可选地，基于第二无线电波的强度，整微波雷达设备的输出功率包括：基于第二无线电波的强度，调整微波雷达设备的天线阵列；通过调整微波雷达设备的天线阵列，以调整微波雷达设备的输出功率。
具体地，调整微波雷达的输出功率通过调整微波雷达的天线阵列而实现，例如：微波雷达天线阵列组内设置有3*3面积、4*4面积和1*1面积的待检测空间对应的天 线阵列。当在1*1面积的地方使用4*4面积对应的天线阵列会造成能耗过大，浪费功率的情况，故根据待检测空间大小的检测，将4*4面积对应的天线阵列修改成1*1面积对应的天线阵列，通过调整天线阵列实现了微波雷达设备输出功率的调整。
可选地，通过调整微波雷达设备的天线阵列来达到更准确的测量效果还包括：在测量时，对处于移动状态中的人或物体进行测量时，首先微波雷达设备向处于移动状态中的人或物体发射无线电波，确定移动中的人或物体是否存在需要检测的内容，例如，人手中是否持有手机，如果手机是需要检测的内容，那么移动中的人就是需要测量的内容，根据人和物体的移动状态，微波雷达设备实时调整天线阵列，以保证调整后的天线阵列发射的无线电波的路径与移动状态中的人或物体的移动轨迹吻合，从而保证可以对移动中的测量内容进行测量。

图2是本申请实施例提供了另一种微波雷达设备输出功率的调节方法的示意图，如图2所示，包括以下步骤：
步骤一，微波雷达设备开始测量，转到步骤二；步骤二，根据无线电波测量空间大小，转到步骤三；步骤三，根据空间大小完成首次功率调节，转到步骤四；步骤四，识别测量空间障碍物属性，转到步骤五；步骤五，根据不同属性对应不同衰减因子进行第二次功率调节，转到步骤六；步骤六，输出功率最优算法评估，完成最后一次功率调节。
