Development and application of imaging infrared systems for earth observation
Since the beginning of 1990 the DLR Institute in Berlin Adlershof has been involved in intensive studies on the development of infrared systems for earth observation (see illustration). Main purpose of these studies from a constructive point of view was the accommodation of these instruments on low cost small satellites for earth observation & space exploration purposes. In conjunction with this activity was to proof the scientific & operational relevance of such systems. The fire ecology was identified in 1994 through the FIRES study as a major candidate for mainly not already covered remote sensing applications. Although high temperature events formed the main focus of the development work during the preceding years, it must be also pointed out as a fact that the high sensitivity of the instrumentation in the classical areas of normal temperature is the basic conditions, achieving outstanding results particularly in forest fire monitoring and detection.
Main characteristics of this instrumentation were the capability to perform quantitative measurement of the fire parameters in the Sub pixel range, and in addition to adapt them automatically in the dynamitic range of the observed scene. Only through this technology was it possible to achieve a high optiminisation of the equipment design.
Based on this concept the development was realised by the following.
Major milestones in the development of IR remote sensing
In particular the ECOFIRE study established a major milestone identifying diverse possibilities for worldwide ecological research into forest fires by a optimal adapted instrumentation.
Based on these efforts and results currently are going on the first steps for the DLR FIREBIRD constellation.
