Radar detection systems of targets in random media using wireless network-based communication system

Radar cross-section (RCS) is one of the important parameters to detect complex targets in random media. Backscattering enhancement (BE) occurs when RCS in random medium like turbulence is double that in free space, this phenomenon is called double passage. There is a substantial difficulty in estimating RCS as a result of the deviation of the BE from the double passage effect. To overcome the prescribed phenomenon, RCS of the target can be calculated from different angles and the average can be taken of these values. This technique will be more powerful if we consider the time factor. In other words, to deal with real time detection, we need to calculate RCS of a target from different angles in parallel. In doing that, I propose to apply wireless network in the communication of a networked radar system (NRS). Connections among different sensors connected to computers that communicate are simulated to provide the average RCS at one time. Two separate problems will be investigated in this project: In the first problem, waves scattered from more complicated targets in random media will be investigated. It is aimed to extend the research of RCS and BE of nonconvex targets with large sizes. In this regard, the scattering problem will be handled by considering the different properties of the incident waves, targets, random media, and polarization of incident waves for 2D and 3D problems. In the second problem, the requirements will be analyzed for communication of a NRS based on a centralized processing model that is similar in its architecture to the client-server model. The system solution takes the form of a computing wireless network in which channels are chosen to give adequate response times and security of services. This network will link together a number of short-range tactical radars, each with associated data processing equipment. Proposed wireless switches are useful not only for civil communication traffic but also for military ones under the condition of congestion. On the other hand, the research on laser radar for target ranging, detection, and recognition has become the one key technology used to evaluate and model the characteristics of scattering from complex targets in the different applications.
