Wind turbine rejection in non-scanning radar

摘要

A signal detector for detecting an information component of a passive radar detection signal, comprises a sampler operable to obtain a sample segment, in time domain, of a radar detection signal, a signal processor operable to identify a relatively high power periodic component of the sample segment signal spectrum in contrast to a relatively low power information component of the sample segment signal spectrum, and a signal rejector operable to window the detection signal with respect to the identified periodic component, to retain parts of the signal not interfered by said periodic component.

1. A signal detector for detecting an information component of a non-scanning radar detection signal, comprising:
a sampler operable to obtain a sample segment, in time domain, of a radar detection signal; a signal processor operable to identify a relatively high power, relatively short duration component of the sample segment signal spectrum in contrast to a relatively low power relatively long duration information component of the sample segment signal spectrum; and a signal rejector operable to window the detection signal with respect to the identified relatively high power component, to retain parts of the signal not interfered by said relatively high power component.
