The radar receiver device comprises two antennae A1 and A2 integrated with each other and operating with two orthogonal polarisations. Two similar receiving channels R1 and R2 are associated with them. The signals X and Y emerging from these two channels are applied to modulators M which receive signals relating to an angle beta in order to produce output signals U and V corresponding to axes rotated through beta with respect to X and Y. After selection of distance and/or speed units CA1, the same signals are processed in order to obtain from them the scalar product whose real part R is used, through an optimal filter FO, to control the value of the angle beta . <IMAGE>
