摘要

A new concept of signal processing is developed to determine the frequency and direction of arrival of a plane wave at a localized receiving point. The system is not restricted at any instant to observation of a subset of the admissible signals through a priori estimates of the received signal; furthermore, no estimate of signal duration is necessary. Two or more linear arrays are used to sample the electromagnetic environment at the receiving point. The signal sets so acquired are combined to synthesize signals of known form from which data related to the parameters of interest are extracted. The knowledge of the form of these signals is used to select preferred data values for computational parameter determination. This method of information management is important in that it supports the development of a measure of quality of the system performance. The measure of quality is in the form of two probability density functions that represent the most general measure of performance. A contribution to the field of Markov processes leads to recognition of a matrix form of the binomial probability density function. A complete theoretical analysis of the processing with two arrays is presented, with examples of the measure of quality for selected cases. The first step in an extension to higher order systems is presented without analysis. A direct analogy with previous efforts in this field illustrates the advantages to be expected of further investigation based on this concept. (Author)
