N2 - This study introduces a method for single-channel imaging at low sampling rates, utilizing Frequency-Modulated Continuous Wave radar combined with space-frequency multiplexing. This approach significantly reduces system complexity and data acquisition demands by encoding scene reflectivity into a single, low-frequency signal. A mathematical framework supporting this technique is developed and followed by an experimental demonstration, where an image is reconstructed using a transmit antenna and a 15-element receive array within the 92–96 GHz band, whose interaction is converted into a single beat signal with a 32 MHz bandwidth.
