Night lamp control method and device based on radar, radar and storage medium

The invention provides a radar-based night lamp control method and device, a radar and a storage medium. The method comprises the following steps: acquiring an echo signal obtained by detecting a bed body surface area by the radar; judging whether the user enters a sleep state or not according to the echo signal, and if the user enters the sleep state, extracting point cloud data from the echo signal; if the signal-to-noise ratio of the point cloud data meets a preset body movement condition and the height value of each point in the point cloud data meets a preset getting-up judgment condition, judging that the user has a getting-up action; if the user has the getting-up action, the night lamp is controlled to work in the first state, otherwise, the night lamp is controlled to work in the second state, according to the method, the night lamp is controlled to be turned on only when the getting-up action is monitored, the situation that the night lamp is mistakenly triggered due to small-amplitude action in the
