Signal detection method and device, electronic equipment and storage medium

The embodiment of the invention discloses a signal detection method and device, electronic equipment and a storage medium. The method comprises the following steps: receiving ultra-wideband echo data through an ultra-wideband circularly polarized antenna, wherein the ultra-wideband echo data comprises a plurality of groups of continuous ultra-wideband echo signals; determining a target ultra-wideband echo signal corresponding to the position of a target object from the multiple groups of ultra-wideband echo signals; performing filtering processing on the target ultra-wideband echo signal to obtain a vital sign signal of the target object; and determining the vital sign information of the target object based on the vital sign signal. The ultra-wideband circularly polarized antenna is used as the transceiving antenna, so that the influence of multipath signals can be reduced, the detection precision of the vital sign information is further improved, the vital sign information of the target object is determined
