Lct. Chang et al., A DATA-COMPRESSION TECHNIQUE FOR SCATTERED FIELDS FROM COMPLEX TARGETS, IEEE transactions on antennas and propagation, 45(8), 1997, pp. 1245-1251
A data compression technique to efficiently compress the scattered fie
lds from complex targets is presented. Since at high frequencies the s
cattered fields from complex radar targets exhibit a highly localized
behavior, the data compression technique is based on extracting and th
en sampling the responses associated with individual scattering mechan
isms. The compression technique preserves the angle as well as frequen
cy variation of individual scattering mechanisms and, thus, leads to s
mall reconstruction error. The proposed technique, however, is a lossy
process in the sense that a tradeoff exists between the compression r
atio and the data reconstruction error. The smaller the data reconstru
ction error, the smaller the compression ratio. The effectiveness of t
he technique is demonstrated by compressing measured scattered fields
of a complex target.
