A compact dual mode seeker is under development at Diehl BGT Defence (DBD) addressing autonomous guidance, target detection and classification/identification for extended air defence (EAD) and ballistic missile defence (BMD). The dual mode sensor consists of an imaging infrared sensor and an imaging LADAR sensor both in snapshot mode. This paper presents the concept of the dual mode sensor and shows the current development status. Critical components such as a compact laser source, fiber-array for image plane sampling, and wavelength selective infrared beam splitter are presented in detail. Single Spot and 3D-LADAR-measurements were performed with a seeker lab-setup to demonstrate the system.
