Employing Vector Radiative Transfer to Estimate RCS of Chaff Cloud in Real-Time

Abstract

This paper employs the vector radiative transfer approach to estimate the real-time radar cross-section of a chaff cloud. Our study focuses on investigating the dynamic radar cross-section of chaff clouds formed within an aircraft-induced chaff corridor. To account for temporal aspects, we assume the chaff cloud's orientation distribution while considering the chaff's intrinsic properties. The estimated results show the vector radiative transfer technique is efficient in capturing the time-varying properties of chaff clouds and swiftly computing substantial quantities of chaff. Additionally, we emphasize the significance of devising an efficient methodology to manage extensive data stemming from chaff clouds, which could potentially amount to millions of data points.
