In this paper, we demonstrate an improvement in the accuracy of a low-cost smart temperature sensor, by measurement of the nonlinear curvature correction at multiple temperature references. The sensors were positioned inside a climate chamber and con

Electro-optical and infrared devices are vulnerable to the increasing threat of dazzle and damage from laser weapons, which will reduce the operational effectiveness of these surveillance devices critical to situational awareness. In this paper, we c

Target and Background Signatures IV.
To validate thermal infrared signature models, we need data from well-characterized targets, typically of simple geometric shape measured under known atmospheric and environmental conditions. An important parameter of the target's signature is the va

Infrared imaging sensors are a vital component of modern military weapons and surveillance systems, which for land operations is dominated by uncooled thermal imagers using microbolometer array detectors. These sensors, just as for all electro-optica

In this paper, we describe the temperature and thermal variations from a painted geometrical target (CUBI) fitted with a network of internally mounted 1-wire temperature sensors. The sensors, which were calibrated in a temperature-controlled oven, we

The polarimetric probability distribution functions (PDFs) of laser speckle for incident linear and circular polarization states have been determined from the measured Stokes parameters for a limited range of targets that may be encountered in remote

The continued interest in bistatic polarimetric radar, particularly for SAR applications, has resulted in the requirement for additional simple, well characterized targets for external calibration. These targets must enable both bistatic and polarime
