Title:
RADAR SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JP2014102235
Kind Code:
A
Abstract:

To provide a radar signal processor for obtaining attributes of a distribution target from reflection waves which have individually arrived from the distribution target in accordance with a plurality of transmission waves whose polarizations are different in which it is possible to accurately and stably obtain the attributes of the distribution target regardless of the configurations and physical distribution of the distribution target.

The radar signal processor includes: dielectric coefficient acquisition means for applying a correction ρ between reflection waves which have individually arrived from a distribution target in accordance with a plurality of p transmission waves whose polarizations are different to an already known correspondence between the correlation ρ and the configurations of the distribution target to specify the configurations of the distribution target, and for acquiring the dielectric coefficient of the distribution target to be determined on the basis of the configurations; and reflection factor calculation means for applying the dielectric coefficient acquired by the dielectric coefficient acquisition means to the whole or a part of a plurality of p radar equations established with respect to the transmission waves and reflection waves of each polarization to calculate radar reflection factors corresponding to the whole or a part of the polarizations as unknown numbers.
