Abstract

Abstract

The length feature plays an important role in the ship target identification. A new algorithm for ship length estimation based on the joint observation of wideband composite bistatic radar is presented, which utilize the mono-/bi-static High-Resolution Range Profiles (HRRPs) and the bistatic spatial geometry relation to estimate the actual length of the ship target with only one-time measurement. Then the estimation errors under different conditions and geometrical constructions are analyzed through Monte Carlo simulations. Finally, the proposed method is validated through typical scene simulation experiments. The results show that when the error of HRRP length is less than 5%, the estimation error of the actual ship length is less than 5%, which provides a new idea for feature extraction and identification of ship targets.
