The given work is devoted to the modern developments in the field of solution the main problems of radiolocation, such as detection of the undistinguished target, selection and recognition targets against the noise, radar clutter, background, interference by new method of radiolocation – full polarization probing. These methods provide the complex protecting of onepositional radio-locator from passive, active and combined hindrances by single technical decision. The output signal to noise ratio can be increased more than 20 dB due to this method.
