Abstract EN
Real-time tracking of maneuvering targets is the prerequisite for continuous imaging of moving targets in inverse synthetic aperture radar (ISAR).
In this paper, the range and azimuth tracking (RAT) method with wideband radar echoes is first presented for a mechanical scanning monopulse ISAR, which is regarded as the simplest phased array unit due to the two antenna feeds.
To relieve the estimation fluctuation and poor robustness of the RAT method with a single snapshot, a modified range and azimuth tracking approach based on centroid algorithm (RATCA) with forgotten factor and multiple echoes is then proposed.
The performances of different forgotten factors are investigated.
Both theoretical analysis and experimental results demonstrate that RATCA is superior to RAT method.
Particularly, when target echo is missing occasionally, RAT method fails while RATCA still keeps good performance.
The potential of continuous imaging with shipborne ISAR is verified by experimental results.
With minor modification, the method proposed in this paper can be potentially applied in the phased array radar.
