In recent years, through the rapid development in personal computer technology, it has become possible to make a radar simulator based on the personal computer. The advantage of the personal Computer aidd radar simulator lies in its cost effectiveness, when comparing with that using the real radar. Although there have been studies carried out to develop radar simulator using PC and the products of thi kind is in the commercial market already, they are all using the mockup of the real radar, and therefore, the price of the simulator is still rather expensive. In this respect, this thesis aims to develop a ARPA radar simulator which is running on the sole PC, so that the students of the maritime educational institution may get ARPA radar training easily and cheaply. The simulator developed in this thesis using Visual Basic is found to run successfully on the 486PC, and it is expected that this new simulator system designed first time in Korea would be used as an easily accessible ARPA radar training equipment.
