Abstract:
1. A radar system comprising: a processor; a waveform generator in control and signal communication with the processor; a plurality of antenna interfaces, each interface in control and signal communication with the processor and the waveform generator; a set of first antennas for transmitting a waveform, each of the first antennas in signal communication with one of each antenna interface; and a set of second antennas for receiving a reflected waveform, each of the second antennas in signal communication with one of each antenna interface; wherein the waveform generator generates a waveform conforming to frequencies of at least two ISM bands; wherein each first antenna transmits a circularly polarized electromagnetic waveform; and wherein each second antenna receives a reflected circularly polarized electromagnetic waveform complementary to the first antennas.
