N2 - In airborne phased-array radar search mode, wide-angle scanning causes the target to occupy different positions relative to the beam center, so the received amplitude is affected by the array pattern, scan loss, and two-way propagation loss. For long-range multi-scattering targets, the echo energy also varies with observation angle, making Radar Cross Section (RCS) measurement more complex than direct amplitude extraction. In addition, clutter can raise peak power, shift range cells, and degrade angle estimation. Thus, this paper develops a simulation model using multichannel angle estimation to compensate beam-scanning loss, and clutter is introduced to evaluate its impact on RCS measurement accuracy. Clutter is introduced to compare RCS before and after compensation, showing its significant impact on measurement accuracy.
