N2 - Joint observation with multiple radars operating on different frequencies is beneficial to classification, identification and catalogue for space objects with multiple radars. Since RCS is sensitive to frequencies, RCS would be considerably different for the same space object measured by radars operating on different frequencies; this effect is not satisfying for task scheduling of joint observation for space objects. A normalized measurement method to acquire RCS which is independent of frequencies is proposed in this paper. Depending on the mapping relation between object RCS sequences and the equivalent ellipsoid, two-dimensional size of the object equivalent ellipsoid is estimated, and then the corresponding projected area is calculated and regarded as the normalized RCS. The dispersion of the normalized mean or median RCS measured by radars operating on different frequencies is smaller compared with the original RCS, using five objects as an example. The analyzing results with real data show the validity of the proposed method.
