Abstract
A radar sensing system includes a transmitter and a receiver. The transmitter is configured to transmit a radio signal. The receiver is configured to receive radio signals that include the transmitted radio signal reflected from objects in the environment. The transmitter and receiver are configured to distribute the signal power over frequency so that it is separated from noise and impairments at DC and low frequencies as may be caused by some radar system components which introduce DC offsets and/or low frequency (e.g. flicker) noise.
