Abstract :

Frequency carries the most important parameters for identifying and classifying signals in electronic warfare systems and measuring them is one of the most important tasks of an electromagnetic support measure. To this end, various receiver structures with different capabilities and features have been proposed; however, given the technology available, it is usually necessary to combine different structures to achieve receivers. Used with the specification and function given. Although analogue receptors are capable of measuring essential parameters, they have limitations on sensitivity and accuracy. Therefore, digital receivers, by removing the limitations, have created a good signal in such systems. Adding multi-signal simultaneous presence detection capabilities and CW signal presence to the receiver structure are among other activities to complete the receiver's conceptual design. In this paper, we investigate the principles of performance, error analysis and finally simulation of receiver frequency moment measurement (DIFM) based on data characteristics. After a comprehensive overview of the proposed receivers for electronic warfare backup systems, we propose the overall structure of the receiver in order to allow it to be used in receivers with appropriate parameters and provide relationships to calculate its performance. To give. We also choose the appropriate estimator by simulation using MATLAB software. Then, by summarizing the material presented, we introduce the structure of the final receiver and, after appropriate mathematical modeling, obtain the overall performance of the system. As we shall see, the introduced receiver structure is capable of meeting the desired receiver specifications in the defined project.
