From: MTRC compensation in high-resolution ISAR imaging via improved polar format algorithm based on ICPF
Simulated experiment with MIG-25 data. (a) RD image. (b) ISAR image after the Keystone algorithm. (c) Original HRRPs. (d) HRRPs after range shift. (e) ISAR image after PFA. (f) ISAR image of shifted signals after PFA. (g) Coefficient of quadratic phase estimated by ICPF method. (h) Entropy map of the ISAR image after MTRC compensation with different rotation angles and centers. (i) Compensated image by the method in ref. [20]. (j) Estimated values under different SNRs. (k) Estimated errors under different SNRs.
