The technology described herein is directed towards a transceiver with beam scanning capability based on leaky wave antenna technology and substrate integrated waveguide technology, along with a metallic covering that determines which direction the antenna radiates signals. The leaky wave antenna can include different respective groups of slot pairs having different respective periodicities, corresponding to different respective beam steering directions. One or more metallic covers can be used to cover some of the slot pair sections, such that the sections under cover behave like a conventional substrate integrated waveguide and the exposed section(s) behave like conventional leaky wave antennas. The metallic covers can be moved as desired, such as attached via magnets. The transceiver can thus steer signals to a wearable or portable device that includes a passive metasurface while mitigating null regions. The slot pairs can be asymmetrical reflection-canceling slot pairs, to achieve broadside radiation while avoiding band-stop effects.

A multi-static synthetic aperture radar using beamformed illumination beams and multiple collection satellites is described. An illumination satellite may be in first orbit and multiple collection satellites may be in a second orbit. The illumination satellite may transmit beam signals (e.g., communication signals carrying modulated data to user terminals) from an antenna array to different beam coverage areas according to a beamforming matrix. Each of the collection satellites may receive reflections of the beam signals. The reflected signals received at the collection satellites may be processed according to the beam signals and beamforming matrix used to transmit the beam signals to obtain an image of a geographical area. In some cases, the collection satellites may relay the received signals for processing via the illumination satellite.
