Abstract:

This is a theoretical study examining the possibility to use a commercial, shipborne navigational radar, for target classification and identification, without changing its electronic signature. The reason for such a modification is that using sophisticated pulse forms for target recognition can betray the users presence and give an intelligence advantage to potential enemy platforms. In order to extract a targets class or identity the data of the radars video detector are fed to a high performance PC with digitizing capability. There the targets class is obtained through a series of transforms, while the targets identity is obtained by computing he targets frequency response to a very short pulse. Through the MUSIC method. While the classification process does not require any changes in the transmitter, in order to obtain target identification in tactically useful ranges it is necessary to increase the transmitters power and add an additional very short pulse.
