It is considered multiposition passive radar to which reception channels get, the hindrances reflected from motionless objects, which level are exceeded much more by level of a useful signal. Without neutralisation of action of hindrances in such situation, reception and processing of signals it is impossible, as weak useful responses to a filter exit mask lateral petals of responses of powerful hindrances. For hyperbolic multiposition radar in which basis measurement of a mutual delay of distribution of signals lies, the way двухэтапной is offered to indemnification of hindrances of this kind. It is shown that this way allows to allocate взаимнокорреляционный the response of useful signals and to make necessary measurements of time delays. Level of indemnification of hindrances, thus, can be high enough, and, at performance of some conditions - indemnification can be full.
