Abstract: A new algorithm for infrared mono-station passive location for a mobile target is presented based on infrared
imaging, series images processing and three dimensional movement analysis. The algorithm results in the relative distance
between the maneuvering target and the measurement station by using the measured information of the infrared imaging target.
It is applicable to such relative motion models between the maneuvering target and the maneuvering measurement station as the
invariable velocity, invariable accleration and variable acceleration and so on with high location precision, small cubage
and great mobility. The correctness and validity of the algorithm are illustrated by both the computer digital simulation and
the semi-practicality visible light imaging simulation. The algorithm is also suitable for visible light imaging mono-station
passive location.
