In the process of creating high-precision systems for the destruction of small-sized ground objects, it is necessary to solve two contradictory tasks: to provide a highly detailed image of the earth's surface, allowing to resolve closely located targets, and to measure their coordinates with high accuracy and to form a law of high-precision guidance on one of them. It is quite difficult to solve this problem using a single-position guidance system.

However, it can be solved by using semi-active trajectory control of observation by a two-position guidance system. Within the framework of such a system, one information (transmitting) position irradiates the target, flying along a trajectory that implements the mode of telescopic synthesis of the antenna aperture at the other – shock (receiving) position, which allows it to provide high–precision guidance to the irradiated target.

In the article, based on the mathematical apparatus of the statistical theory of optimal control, an example of the synthesis of semi–active trajectory control of the observation of transmitting and receiving positions solving the common task of defeating small-sized ground targets is considered.

Within the framework of this example, specific laws of information and shock positions management are obtained and their analysis is given.
