Patent ID: 7701382

Claim:
A method for detecting radar performed within a wireless communication transceiver, comprising: reading pulse information from each of a plurality of radio frequency transceiver receive path first in first out buffers (FIFOs) into groups of arrays, wherein each group of arrays includes a start time array, a pulse width array, and an FM value array wherein the FM values represent an absolute value of a difference of an estimate of a frequency at a start of the pulse and an estimate of a frequency at an end of the pulse as determined by an FM demodulator; combining adjacent pulses in each array wherein, if the difference in start times between two adjacent pulses is less than a specified minimum spacing value, the method includes deleting the 2nd pulse and setting the pulse width for the first pulse equal to the combined pulse width of the two original pulse widths; and setting an FM value equal to the sum of the FM values of the two original pulse widths of the adjacent pulses.
