Abstract

Direct detection laser detection and ranging (LADAR) has been widely used in many specific applications such as precision guidance, machine vision, underwater images, landslides investigations, city modeling, and so forth. One of the most promising methods to design, develop, test and validate a LADAR system is hardware-in-the-loop (HWIL) simulation. LADAR target simulator generates return signals of the simulated targets and background according to the test requirements. One of the key technologies of the LADAR target simulator is target modeling. A target modeling method based on data matching and restoring is pdroposed in this paper, which can provide a feasible way for LADAR target simulator to acquire the information of the target. The coordinate transformation is used to transform the target coordinate data under two or more viewpoint coordinate system into the reference point coordinate system to obtain the whole information of the target. Then, the target coordinate data under the reference coordinate system is transformed into a given viewpoint coordinate system. Furthermore, the deley time and the pulse width are calculated arrcording to a return signal mathematical model. Finally, the effects of the incident angle and target distance on target data are analyzed.
