1. A modular radar system, the system comprising:
a plurality of radar system modules detachably coupled together, each of the plurality of radar system modules having a predetermined output power and output frequency, each of the plurality of radar system modules comprising:
a predefined number of radio-frequency (RF) transmit and receive assemblies coupled to a cooling manifold, each of the predefined number of RF transmit and receive assemblies comprising at least one radiating element that emits electromagnetic radiation;
at least one processor coupled to a mount to control power of the electromagnetic radiation of the at least one radiating element;
at least one controller coupled to the mount to control the predefined number of RF transmit and receive assembly, the power unit and the digital receiver and exciter module;
at least one digital receiver and exciter coupled to the mount to convert RF to digital in receive mode, and digital to RF in transmit mode;
at least one RF beamformer coupled to the mount to generate one or more RF beams; and
a midplane coupled to a) the mount, b) the first processor, c) the second processor, and d) the predefined number of RF transmit and receive assemblies,
wherein a number of radar system modules in the plurality of radar system modules is based on a desired power output for the modular radar system.
