Error Analysis Of Single Channel Switched DF Receivers For Non-Zero-Bandwidth Signals

For direction finding systems, if the bandwidth of the signal is within a certain criterion, the narrowband assumption can provide sufficient analytical accuracy for most situations. However, for the analysis of systems with high SNR and/or high sensitivity, the narrowband assumption can not provide sufficient detail. Furthermore, if the DF system has a switched receiver architecture, the performance of the system is greatly affected by the signal bandwidth rather than the SNR. In this study, for signal with non-zero bandwidth, direction finding performance of the switched receivers was analyzed. Analysis results were compared with the analyzes made using narrowband assumption and supported by the simulation results.
