MIMO (Multi Input Multi Output) methods of PC-HPRF(Phase Coded High Pulse Repetition Frequency) radar have been studied. It is able to be considered that Some orthogonal codes are used for discrimination of each transmitter antennas. Correlations of periodic codes which are used in Radar system generally, however, have some sidelobes in the case that codes are demodulated by 2nd code because this sequence is corresponding to aperiodic basicaly. Three methods to obtain low sidelobe correlation signal using perfect periodic code were proposed in this paper. We choose the Ipatov code as perfect periodic code and several baseband simulation were applied for verifying orthogonal characteristics for each anntena signal. We also compared each methods at viewpoint of system merits. |
