The method of integrated detection, spatial localization and recognition of multiple targets in radio-locators with transmitters of opportunity is developed in the paper. The method is based on using angle information of arrival and scattered signals amplitudes in the probability density function. Characteristic feature of the method is simultaneous detection, spatial localization and recognition of multiple targets. The modeling results in the case of passive radar consisting of four transmitters and one receiver which measures angles, time delays and Doppler frequency shifts for several targets are demonstrated in the article. It is proved that using angle information of arrival provide increasing accuracy of detection and spatial localization as well as decreasing computational time.
