1. A system, comprising:
a first phased array radar assembly, wherein the first phased array radar assembly comprises:
a first plurality of antennas arranged in an array;
one or more circuits, wherein each of the one or more circuits comprises:
receiver circuitry communicatively coupled to the first plurality of antennas,
the one or more circuits being operable to receive a signal via at least one of the first plurality of antennas, the signal being indicative of a characteristic of an environment, where the signal is used by a processor to generate a multidimensional representation of a scene based on the characteristic of the environment,
wherein at least one of the one or more circuits includes or is coupled to at least one digital signal processor (DSP) operable to:
 apply a phase shift on the signal; and
 combine the phased shifted signal with a second signal to achieve beamforming.
