PROCESSING RECEIVED RADIATION REFLECTED FROM A TARGET

摘要

A method of and apparatus for processing received radiation (e.g. RADAR radiation) reflected from a target (101), the method comprising generating (200) a set of predicted targets, the set of predicted targets comprising at least one member, each member representing a state of the target (101), generating (201) a predicted waveform for the radiation for each member dependent upon the state of the target (101), and comparing (202) each predicted waveform with a waveform of the received radiation to determine the accuracy with which the state of the target (101) represented by the member for which the predicted waveform was generated matches an actual state of the target (101).
