| description | PURPOSE:To make it possible to perform the clear detection of a target by avoiding the jamming of an arrival interference wave, by emitting the radar transmission signal of the polarized wave crossing that of the arrival interference wave from a radar antenna. CONSTITUTION:The characteristic analysis of a polarized wave is performed by such a method that the amplitude and phase of a horizontal component H are compared with a vertical component V as reference by a signal processing means. According to this result, the radar transmission signal generated in a transmitter 4 is synthesized to the polarized wave crossing that of an arrival interference wave at right angles by polarization wave synthesizers 10a-10n to be emitted from a radar antenna 1. Because the radar transmission signal strong in autocorrelation having a signal mode unaffected by jamming of the interference wave is reflected from a target to be received by a receiver 5 while guided thereto as mentioned above, the jamming of the arrival interference wave is avoided by a signal processor 6 and the detection of the target can be performed. |
