Introduction

Josiah T. Perrin is an inventor associated with Nashua, New Hampshire, and BAE Systems Information and Electronic Systems Integration Inc. His patent work concerns radar warning receiver technology and the analysis of threats detected by such systems.

Latest Patents

Perrin is named on 1 patent: “System for Design of a Radar Warning Receiver.” The invention describes techniques for analyzing the probability that a radar warning receiver (RWR) will intercept a threat signal. It calculates cumulative probability of intercept by comparing the receiver’s scan schedule with threat illumination periods, and estimates the mean time between overlaps.

The disclosed approach also adjusts the receiver’s dwell revisit time according to its utilization and whether the calculated probability of intercept meets a required threshold. It can modify the scan schedule to let multiple threats share receiver dwells, taking their pulse repetition intervals and illumination durations into account. Finally, it adjusts the estimated time between overlaps to help achieve a required time to confirmed track.
