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