Signal agnostic matched filter parameter estimator

摘要

A system and method for detecting unknown signals is presented. A system includes a receiver, a multiplier logic, integrator logic and a peak detection logic. The receiver receives a first radio frequency (RF) input containing an unknown signal and first noise and a second RF radio input containing the same unknown signal and a second noise. The second RF input is orthogonally polarized with respect to the first RF input. The multiplier logic multiplies the first RF input with a conjugate of the second RF input to produce a multiplied signal. The integrator logic integrates the multiplied signal to product an integrated signal. The peak detection logic determines a coarse time of arrival (TOA) of a unknown signal located in the integrated signal based, at least in part, on a peak power in the integrated signal.

1. A system for detecting radar comprising:
a receiver configured to receive a first radio frequency (RF) input containing a radar signal and first noise and a second RF input containing the radar signal and a second noise, wherein the second RF input is orthogonally polarized to the first RF input; a multiplier logic configured to multiply the first RF input with a conjugate of the second RF input to produce a multiplied signal; an integrate logic configured to integrate the multiplied signal to produce an integrated signal; and peak detection logic configured to determine a coarse time of arrival (TOA) of a radar signal located in the integrated signal based, at least in part, on and a peak power in the integrated signal.
