ACTIVE SONAR WITH OBJECT CLASSIFICATION Russian patent published in 2014 - IPC G01S15/00 

FIELD: physics.

SUBSTANCE: active sonar with object classification comprises series-connected control device, probing signal generator, generator and acoustic radiating antenna, series-connected acoustic receiving antenna, device for processing echo signals from an object and classification parameter measuring device, and a display. The active sonar also includes series-connected Papost_N determination unit, where Papost_N is the a posteriori probability density of the class of the object on the current transmission N, Papost_F determining unit, where Papost_F is the a posteriori probability density of the class of the object on the set of transmissions F, and a unit for making a decision on the class of the object based on the set of transmissions, a Papr storage unit, where Papr is the a priori distribution density of the value of the classification parameter.

EFFECT: high probability of correct classification of a detected object by enabling determination of the class of a detected object based on a set of transmissions.
