Abstract: A radar assembly for linear and nonlinear radar transmission and reception comprising a signal generator; at least one filter operatively connected to the signal generator; a transmitter operatively connected to the at least one filter for transmitting radar signals; a receiver operative to receiving received signals comprising linear and nonlinear responses from the reflected transmitted signals; the receiver comprising a first channel for processing the linear response of the received signal; a second channel for the processing the nonlinear response of the received signal; at least one switch operative to select one of the first or second channels; at least one high pass filter operatively connected to the second channel to attenuate the linear response; at least one amplifier to amplify the nonlinear response; and at least one display operatively connected to both the first and second channels for displaying both linear and nonlinear responses.

Abstract: A spectrum sensing radar system including a spectrum power sensing module configured to sense electromagnetic signal powers in a plurality of sub-frequencies and generate a sensed power set including a plurality of sensed electromagnetic signal powers corresponding to each of the plurality of sub-frequencies; a multi-objective function module configured to receive the sensed power set and calculate a first objective function for each of the plurality of sub-frequencies, wherein the first objective function includes a power function divided by an empirical measure of interference of the sensed power set to form a signal plus noise objective function for a sub-frequency of the plurality of sub-frequencies, and wherein the power function further includes a peak transmit power of the radar system multiplied by a gain of an antenna of the radar system, multiplied by a wavelength of a carrier of the sub-frequency.
