Long-time integration is an effective way to strengthen the weak signal from low-observable target. However, the performances are affected by the range and Doppler migrations during the long observation time. In this paper, Doppler characteristics of a maneuvering target with high-order motion are studied and a novel transform, i.e., high-order generalized Lv's distribution (HGLVD), is proposed to...
High-speed, low-observable, and maneuvering target detection is always the difficult problem for the early warning and detection of space target, ballistic target, and passive radar signal processing. The high-order motion information of maneuvering target is employed in this paper, such as acceleration and jerk. Accordingly, several long-time coherent integration methods are demonstrated and illustrated,...
