Patent ID: 7403153

Claim:
A method of processing a radar return signal, comprising: generating a first array having time sample elements with respective time sample values associated with the radar return signal; processing the first array to detect an interfering signal in the time sample elements, wherein the processing comprises: generating a second array having second array elements with respective second array values associated with the time sample values, wherein the second array values comprise at least one of slope values generated from differences of the time sample values, higher order derivative values generated from differences of differences of the time sample values, or power values, each power value generated by squaring a respective out of the time sample values; determining, from among the second array elements, second array elements indicative of the interfering signal, wherein the determining comprises: generating at least one threshold associated with the second array values; comparing the second array values with the at least one threshold; and detecting that the interfering signal exists if at least a selected number of the second array values exceed the at least one threshold; and identifying time sample elements in the first array indicative of the interfering signal by one-to-one mapping at least one of the second array elements indicative of the interfering signal to a corresponding at least one of the time sample elements, wherein the mapping does not alter the time sample values of the first array; and removing, from the same first array having the same time sample elements and the same time sample values, the identified time sample elements indicative of the interfering signal.
