Below, real recorded echo data from a large civil aircraft and a feeder liner on a VHF-band surveillance radar will be taken to perform the analysis.
Moreover, from the figures one can still see that the LFFDs and LGFs of the large civil aircraft are greater than those of the feeder liner as a whole, because the large civil aircraft often has intenser nonrigid vibration and attitude change than the feeder liner, and its JEM effect is also more distinct than that of the feeder liner.
Figure 2 shows the distributing circumstances of the 2-D features composed of the LFFDs and LGFs of echo data from the two types of targets, with "x" and "o" denoting the feeder liner and the large civil aircraft respectively.
