For multiposition radars operating in a non-cooperative mode with one transmitting and a swarm of receiving elements, the derivation and study of the form of the generalized uncertainty function (GUF) in terms of spatial coordinates is relevant. The GUF criterion can be generalized to apply swarm optimization methods to cooperative multiposition radars and MIMO radars, including those on mobile carriers.

The targets are to derive and investigate as a criterion for the swarm optimization the GUF for a particular case of a non-cooperative multiposition radar with a coherent burst multi-frequency sounding signal. In this case, each receiving position selectively in frequency receives the signal of its burst pulses, and it is natural to consider the set of such positions as a swarm of receiving elements.

For a non-cooperative multiposition radar, using the theoretical expression for the GUF in the case of a fixed point target, two-dimensional topographic diagrams of the GUF in the «range–azimuth» plane are determined. They are compared for different variants of regular and random arrangement of MP radar receiving elements for two wavelengths at medium operating frequencies.

The presence of the main maximum of two-dimensional QUF diagrams «range–azimuth» at the target coordinate point, which exceeds the side maxima in intensity, is shown, which is a prerequisite for using 2D GUF diagrams as a criterion for swarm optimization of the receiving positions.
