US 12,659,211 B2 · Detection of in-band interference

Abstract

A radar device includes processing circuitry to perform operations to identify corrupted data samples in an initial time-domain data set generated from return signals reflected from a target object and also signals from an interfering object causing the corruption. The processing circuitry also performs operations starting on the initial time-domain data set to generate reconstructed data corresponding to the corrupted data samples. An uncorrupted time-domain data set is then generated based on the initial time-domain data set and the corrupted data samples, and repaired time-domain data set is generated based on the uncorrupted time-domain data set and the reconstructed data. The operations performed include thresholding, transforming, inverse transforming, subtracting, and/or combining. The processing circuitry may be hard coded and/or be configured to execute software instructions stored in a memory to perform the processing.

Dependent claims

A non-transitory medium containing instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to:

generate, based on a first time-domain data set including a plurality of data samples, a frequency-domain data set that includes first frequency components having respective magnitudes below a threshold and second frequency components having respective magnitudes above the threshold;
process the first frequency components to identify data samples in the first time-domain data set affected by interference;
apply an inverse transform operation to the second frequency components to generate a second time-domain data set;
and
generate, based on the identified data samples and the second time-domain data set, reconstructed time-domain data corresponding to the identified data samples.
