7 Signal Detection Processing

Now that the fundamental concepts behind adaptive array processing for HF applications have been covered, it is time to move into the meat of this work, specific algorithms for processing the data collected by a multichannel HF sensor. This chapter begins the tour, covering many of the important methods for detection; that is, processing the set of array element outputs to declare that a new signal has appeared among the myriad of other signals present in the HF signal environment.
