New Sensor Paradigm for Future Combat Systems
Abstract
Highly sensitive and robust sensors are a fundamental component of modern science and engineering; with particular relevance to military applications. Stringent requirements posed by the Future Combat Systems (FCS) on real-time diagnostics from remotely sensed raw data, are only increasing the demand for fast, responsive, and accurate sensors. Basic to all measurement devices are inherent data errors associated with uncertainties and background noise. Turn-key, single-function sensors are designed to provide accuracy and repeatability for a specific, directly measured quantity. However, if these measurements are used to infer other physical quantities, special care must be taken. Indeed, in most applications, data differentiation is applied within the predictive process, sometimes even unbeknown to the user. Unfortunately, upon differentiation, the noise that affects all measured physical quantities is dramatically amplified. Refining the measurement (i.e. increasing the sample density) exacerbates the problem even further, because the increase in accuracy due to finer sampling is wiped out by the cumulative adverse effect of the numerical differentiation. In this paper, we propose the development and implementation of a new, rate-based sensors paradigm that would enhance and secure the US military strength.
