Abstract: PURPOSE: A calibration and validation method of an active multi-polarization radar system is provided to obtain a correction constant using a reflected signal reflected in a system without installing a reference target on a field, thereby implementing calibration and validation even in an observation environment where the installation of a reference target is not easy, and to facilitate the reduction of costs and time compared to the existing calibration and validation techniques using the reflected signal in the radar system. CONSTITUTION: A calibration and validation method of an active multi-polarization radar system includes the following steps: a step of constructing a radar system, equipped with a circuit oscillating an electromagnetic wave which has multiple polarization states, and an antenna receiving the electromagnetic wave; a step of performing reference target observation for all the observation directions, desired to be observed on a field, of the radar system in an electromagnetic shielded room using the radar system, and constructing a database thereof(S2); a step of performing radar system observation for a newly defined reference point in the electromagnetic shielded room(S3); a step of performing radar system observation for a new reference point on a field, and then performing observation for a desired target(S4); a step of calculating a correction constant through the ratio of observation values to the reference point performed in the electromagnetic shielded room and on the field(S5); a step of constructing a database for the reference target on a field using pre-constructed database materials for a reference target and the correction constant(S6); and a step of calculating the system noise from the constructed database for the reference target on a field using a theoretical back-scattering coefficient for a reference target(S7,S8). The correction constant defines a reflected signal caused by the discrepancy of the threshold values on the junction of the radar system circuit transmission line and the antenna, as a reflection loss, and the newly defined reference point is the junction.
