POLARIZATION RADAR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an efficient polarization radar device capable of simplifying a circuit.

SOLUTION: Either of a vertically polarized wave transmitted from a vertical transmission antenna 16 and a horizontally polarized wave transmitted from a horizontal transmission antenna 20 is delayed in comparison with the other. The delay is in a range wherein positional movement of an object can be neglected. Each beat signal received by a vertical reception antenna 22 and a horizontal reception antenna 24 and acquired by multipliers 28, 30 is subjected to frequency analysis by a signal processing part 34, and four polarization components are acquired separately by utilizing the fact that each beat signal frequency is different based on delay information.
