The article is devoted to the integrated quantitative assessment of the impact of factors that worsen the potential resolution of the radar with synthetic aperture. Objective factors that enhance the synthesized radiation pattern, are, firstly, the differences in shape pattern of receiving and transmitting antennas from the U-shaped. Secondly, the averaging of the reflected signal at the receiving antenna aperture. And, thirdly, is not perfect alignment of the spherical wavefront of transmitted signals. Numerical evaluation of the degree of expansion of the synthesized pattern simplifies the calculation of the actual pattern of the antenna, which will provide the required resolution to track range radar with synthesized aperture.
