Coherent integration method for high‐speed target detection using angular inverse rotation transform

High‐speed target often induces severe across range unit problem in the long‐time coherent integration (LTCI). This paper designates the bottom‐right corner of the 2‐D compressed signal as the coordinate system origin. It establishes a novel angular inverse rotation transform that accurately correct...

Zusammenfassung:	High‐speed target often induces severe across range unit problem in the long‐time coherent integration (LTCI). This paper designates the bottom‐right corner of the 2‐D compressed signal as the coordinate system origin. It establishes a novel angular inverse rotation transform that accurately corrects target's trajectory to the final location and achieves signal energy accumulation. Numerical simulation experiments and real‐world measured data confirm the effectiveness of the proposed method.
