Abstract
This paper proposes a robust detection statistic for signals whose parameters are uncertain. Standard detection schemes generally use time domain correlation which can be related to correlation based on the Wigner-Ville distribution by Moyal's identity. This paper shows that a more robust detection statistic is achieved by using generalised patterns in time-frequency space and deriving a non-linear time domain correlation. The performance of the robust detection statistic is evaluated with the aid of receiver operating curves, two robust detection examples are given.
