Abstract: Techniques are disclosed for cross-polarization-based object detection and classification. One example includes a system implemented for cross-polarization-based object detection and classification. The system includes a first transmitter antenna configured for radiating a first millimeter wave electromagnetic signal, where the first millimeter wave electromagnetic signal including a first polarization. The system further includes a first receiver antenna configured for receiving a second millimeter wave electromagnetic signal, the second millimeter wave electromagnetic signal including a second polarization. The system further includes a processing circuitry configured to detect an object based at least in part on the second millimeter wave electromagnetic signal, the object being impacted by the first millimeter wave electromagnetic signal to cause the second millimeter wave electromagnetic signal to reflect off the object.
