The problem of radar imaging of an object which is moving relative to the coherent bistatic radar is under consideration. Such a radar system is arbitrarily spatially situated. Radar image is formed due to inversed aperture synthesis by phase-coherent accumulation of the reflected signal. In the report the expression for the function characterizing the resolution of the system is obtained. The analysis of this expression for either active and passive radar systems showed the possibility to subdivide the effect for 2 parts. The first part is associated with the aperture synthesis in plane P of the transmitter, the receiver, and the object. THe second part is associated with the synthesis in the ortholognal plane. Careful analysis of the expression was made for the linear uniform movement of the object. It is shown the best resolution in the direction orthogonal to plane P takes place when the velocity of the object is orthogonal to plane P. The appropriate expression for the resolution ability is obtained.
