Statistical Cross-Correlation Algorithms for Temporal Pulse Profiles
Fred A. Dilkes · Defense Technical Information Center (DTIC) · 2004
Two statistical techniques are presented for comparing temporal pulse trains received from an Electronic Support receiver to a priori templates representing the expected behaviour of radar signals. The techniques implement a specialized cross-correlation procedure and incorporate the effects of non-cumulative jitter. A theoretical basis is presented in which the signal of interest is modeled to be present in a noisy channel. The channel noise may include the failure to detect some expected pulses along with the detection of unexpected pulses. The methods are compared to the more straightforward approaches based on cross-correlation histograms and a simulated example scenario is presented.
