This paper describes some algorithms for radar imaging and radar image processing with practical applications in target recognition. A radar-computer interface to digitize and to input signals from incoherent marine surveillance radar into computer as well as specialized signal processing to reduce the amount of information that will be recorded into the computer for further processing is described. Some experimental results that present digitized signals as images, improve their quality and extract more information about the target of observation are demonstrated. The availability of more information about the targets allows to predict their manoeuvring features and hence to improve the targets tracking. Experiments illustrate the ability of radar target recognition to improve tracking and as such to increase the safety of navigation at sea.
