Interference Cancelation Analysis
The space-time characteristics of HF signals reflected by the ionosphere have been analyzed and modeled from a signal-processing perspective in Chapters 68. The physical phenomena that contribute to the observed signal characteristics are clearly of scientific interest, but the more pragmatic question arises as to the practical impact of space-time signal distortions in operational OTH radar systems. The first objective of this chapter is to present the results of a case study that demonstrates the influence of such distortions in a key OTH radar signal-processing application. Specifically, this case ...
