The present research revisited to estimate and measure acoustic scattering from a rigid or elastic cylinder in air medium. Though the complex analytical formulation has been well established to estimate back scattering from a rigid and elastic cylinder, however, it is quite complex in nature for real-time design from industrial prospective. The present research aims to design and develop an indigenous cost effective instrumentation to measure the acoustic back scattering or target strength of an object for air medium. A customized rotating microphone boom has been designed by using a stepper motor and necessary fixtures. The measurement has been taken in discrete points on the trajectory motion of the probe in equal interval of angular moment in a portable anechoic chamber. The challenges of offset, noise suppression and vibration suppression during measurement have been addressed in detail. Next, the acoustic scattering from a rigid cylinder has been estimated analytically and numerically. The experimental investigation revels the appropriateness of the measurement technique to measure back scattering which is a novel attempt in its own domain first time. Summarizing, the analytical, numerical and experimental results agree to each other up to large extent and from which it can be inferred that the demonstrated numerical analysis and measurement are suitable enough to estimate acoustic back scattering of any object.
