Abstract
This report investigates the applicability of a time-domain technique to estimate the fuzing location in the electrostatic detection problem. This preliminary study is restricted to the case of an ideal point charge response for a short circuit longitudinal sensor, and a given miss distance. The procedure uses a combination of a Enear smoothing filter and a non-linear median filter to estimate the fuzing location in noisy conditions. The robustness of the technique to additive white noise distortions is also investigated. Initial results show that the time-domain analysis technique is promising; the error obtained in the estimation may be kept to within 10% of the true fuzing location for a Signal-to-Noise Ratio (SNR) greater than 5.41 dB (i.e., for an additive noise power less than 0.019) in 86% of the distortion levels investigated.
