  • Systems and methods for modular radar systems
    Patent number: 11808879
    Abstract: A system and apparatus is provided for a modular radar system. The modular radar system can include a plurality of radar system modules that can be detachably coupled and can include a configurable number of radio-frequency (RF) transmit and receive assemblies. The RF transmit and receive assemblies can include radiating element(s) that emit electromagnetic radiation. The plurality of radar system modules can also include at least one processor coupled to control power of the electromagnetic radiation and/or at least one controller to control the RF transmit and receive assembly, the power unit and the digital receiver and exciter module, at least one digital receiver and exciter to convert RF to digital in receive mode, and digital to RF in transmit mode, and/or at least one RF beamformer to generate one or more RF beams.
