Frequency management in multiposition radar systems

In this paper we propose and study the frequency management algorithm for closely-spaced multiposition radar systems. The aim of the work is to develop an investigate algorithm for preventing mutual interference of closely-spaced radars, that can be done by proper use of limited frequency resources. We propose to achieve minimization of interference by creating of frequency schedule for each radar. To do this, we propose to predict conflicts, and find time intervals, where all conflicting radars can have different frequencies and therefore conflicts can be resolved by frequency reallocation. The numerical simulations were done to test performance and computational load of the proposed algorithm.
