/Detection Of In-band Interference
Abstract

An example system includes a radar receiver to receive radar signals including interfering radar signals crossing an in-band frequency range of the radar receiver, and process the received radar signals to form processed analog radar signals; an analog-to-digital converter (ADC) coupled to the radar receiver to sample the processed analog radar signals to generate an initial time-domain data set; and processing circuitry coupled to the ADC. The processing circuitry is operable to receive the initial time-domain data set; perform a set of operations including two or more of a forward transform operation, an inverse transform operation, a low threshold operation, a high threshold, a subtraction operation, a data removal operation, and a data reconstruction operation; identify, based on the set of operations performed, data affected by the interfering radar signals; and generate a repaired time-domain data set in which the data affected by the interfering radar signals is removed.
