Paper Abstract

Research work related to the design and use of anti-radiation missiles (ARM), and any systems intended to protect radar and other radiation-emitting installations against ARMs, requires access to theoretical and physical models of direction finding devices, which are used in guidance systems installed in the aforementioned missiles. In this work, the authors present the concept of an electromagnetic source seeker working in the microwave band. In the solution presented herein, the direction finding is accomplished using the phase method. Phase analysis of signals emitted by the observed microwave source is relatively fast due to the quadrature configuration of the microwave phase discriminator used for this purpose. During an attack, an anti-radiation missile moves at great speed, which exceeds 1000 m/s. Due to this fact, the missile needs to be equipped with systems, which are capable of estimating the direction of the targeted source, and which can update the relevant information as quickly as possible. Such properties in the presented concept were achieved by using comparators with analogue inputs and logical digital (0/1) outputs. As a result, the information from the direction finding channel is obtained in a digital format, with the number of bits (the resolution) being dependent on the number of applied comparators. The authors therefore assume that a coarse direction finding will be used when the deviation between missile trajectory and the direction of target source is relatively large, whereas the more precise target location estimation algorithm will be used when the trajectory of the missile is matched (within established limits) to the direction of the emission source.
