Title: Radio wave azimuth measuring system
Inventor: TAMAI KAZUKI
IPC: G01S3/40
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To correctly measure the azimuth of an incoming radio wave by performing the correlation arithmetic of a self-antenna pattern and a detected waveform every frequency by receiving an output of a detecting means, and detecting the maximum value after the correlation. SOLUTION: A polarization signal (one of H polarization and V polarization) selected by a selector 8, is converted into an IF frequency by a receiver 3, then detected by a detector 4, and entered into a correlator 12. An output of the detector 4 is compared with a former detected signal by a comparator, to compare which polarization has a bigger value. Then the selector is switched, so that the priority is given to the H polarization or the V polarization as the result of the comparison. A pattern reading part 11 is similarly switched. In a next stage, the process for receiving only the polarization having the priority, by the receiver 3, detecting the same by the detector 4, and comparing the same again by the comparator, is repeated.  As mentioned in the above, the azimuth where the maximum value can be obtained by the correlation arithmetic, can be obtained every polarization, by performing the correlation arithmetic on every H polarization and V polarization.
