In a previous paper "Effects of Flow Field Aerodynamics on Imaging Sensor Resolution" - SPIE 1977, it was shown that various flowfield phenomena can degrade sensor performance by causing air density variations. These phenomena were identified (Figure

The non-uniform and fluctuating air density field surrounding a high performance aircraft can significantly affect the performance of visual infrared imaging sensors. This paper addresses each of the classic types of flow field phenomena and develops

A dynamic target acquisition analytic model for a Variable Acuity Remote Viewing System (VARVS) was developed and experimentally verified. The model was then used to compute target acquistion capability of an infrared version of the VARVS and convent

Our concern is with payload requirements and moldline conformity of tactical reconnaissance aircraft. We have observed the size and weight of photo reconnaissance sensors continually increase while other avionic equipment has shown an opposite trend.
