Using Acoustic Beamforming for Pass-By Noise Source Detection

This application note discusses a technique known as beamforming for determining noise location of passing vehicles. The technique has several challenges including simultaneous acquisition of a large sensor array, advanced signal processing and storage of extremely large data sets, and the environmental considerations required for operating outdoors on a test track. This application note recommends best practices for performing beamforming and walks through the complete system required from the test environment to the sensors to the math, analysis, and data storage with the goal of the reader being able to apply the technique.

Bridging the Armament Test Gap

An armament test gap exists today across legacy 4th and 5th generation aircraft due to the inability of current generation test equipment to adequately test the armament required to support smart weapons. The MTS-3060 SmartCan™ Universal O-Level Tester represents a paradigm shift away from the traditional one-for-one test equipment replacement approach and a quantum leap in capabilities available to maintainers on the flightline who are working within the constraints of shrinking budgets.

Implementation of Real-time Spectrum Analysis

The keys to real-time spectrum analysis are to provide parallel sampling and FFT calculations so the data acquisition continues while the FFT’s are performed, and to provide fast enough DSP processing of FFT algorithms to keep up with the sample rate at the input. This white paper discusses the technical implementation of the real-time process in the Rohde & Schwarz real-time analyzers, and the applications for use of this analysis capability in the troubleshooting and test of modern designs.
