LASA DATA ANALYSIS AND MCF SUPPORT
Abstract
With the objective of determining optimum design criteria for predetection multichannel filters for use at the subarray level at the LASA, a study was conducted of the characteristics of the ambient noise fields and instrument responses of five selected subarrays. Based on the measured characteristics of the noise fields and instrument responses, 14 multichannel filters were developed and compared as to degree of improvement in signal-to- noise ratio. A multichannel filter, of a design determined by the comparison experiments to be optimum for subarray predetection filtering, was developed for each of five subarrays. Five multichannel filters of a slightly different design also were developed. These multichannel filters, and certain others of interest, were punched on paper tape for on-line evaluation with the Digital Multichannel Filter System at LASA. A processing procedure for detecting signals at either subarray or full-array level is recommended and illustrated by application to selected events at those subarrays under consideration.
