Space-Based Laser Systems Training
Space-Based Laser Systems Training Course Description
This two-day short Space-Based Laser Systems Training reviews the underlying technology areas used to construct and operate space-based laser altimeters and laser radar systems. The course presents background information to allow an appreciation for designing and evaluating space-based laser radars.
Fundamental descriptions are given for direct-detection and coherent-detection laser radar systems, and, details associated with space applications are presented. System requirements are developed and methodology of system component selection is given. Performance evaluation criteria are developed based on system requirements. Design considerations for space-based laser radars are discussed and case studies describing previous and current space instrumentation are presented. In particular, the development, test, and operation of the NEAR Laser Radar is discussed in detailed to illustrate design decisions.
Emerging technologies pushing next-generation laser altimeters are discussed, the use of lasers in BMD and TMD architectures are summarized, and additional topics addressing laser radar target identification and tracking aspects are provided. Fundamentals associated with lasers and optics are not covered in this course, a generalized level of understanding is assumed.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
