Abstract
This memorandum describes two infrared targets for in-flight FLIR evaluation developed at DREV. The first one consists of a 2X2 m blackbody surface capable of producing a temperature contrast up to 30C. This source is equipped with a four-bar pattern, that can be placed in front, to perform a standard minimum resolvable temperature differeance (MRTD) test on aircraft-mounted forward looking infrared (FLIR) systems. The MRTD methodology is explained and the performance of the infrared target is presented. The second target consists of a narrow hot bar source of 2.4 m long heated up to a temperture of 100C. This source can reproduce, in the field, the effect of a slit in a laboratory allowing line spread function (LSF) measurement during a flight.
