The method includes emitting, by a plurality of transmitters oriented in a respective plurality of directions, signals to produce uniform millimeter wave illumination of the three-dimensional space. The method includes determining object data including a direction, a phase, and a timing of signals reflected from one or more objects within the three-dimensional space. The method includes detecting, by a processor, the one or more objects in the three-dimensional space based on the object data. The method includes rendering, by the processor, an image corresponding to the one or more detected objects. ## Claims ### Claim 1 A detection system for a three-dimensional space defined by four walls, the detection system comprising: a plurality of transmitters oriented in a respective plurality of directions and configured to produce uniform millimeter wave illumination of the three-dimensional space, with at least one transmitter of the plurality of transmitters being located on each of the four walls;
