Low power, space combined, phased array radar

摘要

A radar system including a plurality of mini radars may be conformable to a structure that it is attached or built into. A radar system includes a clock, a plurality of frequency modulated/continuous wave (FM/CW) radar units in signal communication with the clock and a processor in signal communication with the plurality of FM/CW radar units. Each of the plurality of FM/CW radar units includes a row of antenna elements.

主权项

1. A method comprising:
generating, by a clock on a first side of an antenna circuit board, a single clock the antenna circuit board comprising at least one isolation wall; sending the single clock signal to a plurality of radar units mounted on the first side of the antenna circuit board, each of the plurality of radar units comprising a frequency modulated/continuous wave (FM/CW) or Pulse Compression radar unit, each radar unit of the plurality of radar units comprising a column of two or more antenna elements mounted on a second side of the antenna circuit board, wherein the at least one isolation wall of the antenna circuit board is located between a pair of adjacent columns of the antenna elements, and wherein the first side of the antenna circuit board is opposite the second side of the antenna circuit board; generating at least one control signal at a first processor in signal communication with the plurality of radar units; transmitting radar signals from the plurality of radar units based on the at least one control signal; receiving radar reflection signals at the plurality of radar units; and sending the radar reflection signals to a second processor in signal communication with the plurality of radar units.
