Abstract Details

2013, Master of Science, Miami University, Computational Science and Engineering.
An Electronic Warfare (EW) receiver is part of an electronic intelligent (ELINT) receiver. It is under intensive development to adapt to the ever-evolving complex signal space. EW receivers are required to detect and characterize multiple incoming signals in real time and the receivers are designed without any prior information of possible incoming signals. It is therefore desired to have a wide working bandwidth. There are two parts in this thesis: Bandwidth improvement in EW receiver development and the creation of an encoder to detect unknown signals. One scheme to improve the wideband capacity is through the implementation of in-phase and quadrature (I/Q) module. With this implementation, the working bandwidth doubles. However, the low instantaneous dynamic range due to imbalance I/Q module prevents this from being useful. An algorithm to mitigate the imbalance effect was recently developed. Part of this thesis is to study the mitigation algorithm and implement it for real time processing using a field- programmable gate array (FPGA). The other part of this thesis is to create an encoder for multiple signal detection. Three different radar signal types, continuous-wave (CW), linear chirp and binary phase shift keying (BPSK) are considered in this study.
