1. A system for radar, comprising:
an antenna array,
wherein the antenna array comprises at least two pairs of non-intersecting arc configurations implemented on a circuit board,
wherein a set of transmitter antennas and a set of receiver antennas are arranged in a first arc configuration of a pair of the at least two pairs of non-intersecting arc configurations,
wherein the set of transmitter antennas comprises N transmitter antennas and the set of receiver antennas comprises M receiver antennas,
wherein a first end of the first arc configuration is positioned on the circuit board closer to a center point of the circuit board than a second end of the first arc configuration,
wherein a first end of a second arc configuration of the pair of the at least two pairs of non-intersecting arc configurations is positioned on the circuit board closer the center point of the circuit board than a second end of the second arc configuration;
wherein the first arc configuration and the second arc configuration are not abutting; and
wherein the first arc configuration and/or the second arc configuration are positioned on the circuit board to not overlap the center point.
