“…The auxiliary chaffs sprinkling device disclosed 24 was used to release a large amount of chaff from the aircraft and take advantage of the airflow generated by the aircraft propeller or wing to help the chaffs spread rapidly. Žák et al measured the aerodynamic pressure distribution around the helicopter to reasonably arrange the chaff delivery mode 25 and also measured the chaff physical characteristics 26 . But obviously, it is difficult to test.…”

This paper equates chaff clouds to dipole clusters and studies the electromagnetic scattering problem of dipole clusters based on the linear method of moment (LMM) that solve the electric field Integral equation with the pulse basis function. Firstly, the radar cross section (RCS) of three dipole elements is calculated. The dipole element is divided into 11 segment line units using pulse basis functions. The actual chaff clouds are modeled as two nearest dipole cluster models, which are cubic dipole cluster with uniform distribution formed and spherical dipole cluster with Gaussian distribution formed. The total RCS and total E‐Field magnitude of two dipole cluster models were calculated. Finally, two physical models are constructed based on the simulation models and an experiment is designed. The electromagnetic scattering characteristics of the two models are measured, which verifies the accuracy of the simulation results and the operability of the experiment.

“…La RCS máxima de un dipolo viene dada por la relación en metros al cuadrado , LKk ≈ 0,856 m h . Sin embargo, dado que el dipolo puede tener una orientación aleatoria en 4g estereorradianes, obtenemos que la RCS media vendrá determinada por la expresión , ≈ 0,172 m h (Butters, 1982;Hannen, 2014;Zak, Gregor, Dvoracek, & Papez, 2018).…”
