Photonic MEMS technology as it pertains to adaptive coded aperture sensing is an emerging technology offering an
increase to imaging performance compared to a fixed system in the EO/IR wavelength region. In this paper we address
the effects of potential manufacturing yield and defects. A 1-d first order optical model is developed in an attempt to
correlate the optical/system performance to the manufacturing defects and yield output. The imager is found to be
extremely robust to both random and correlated failures in the coded aperture, so long as the aperture code is adapted to
the aperture failures.
The Defense Advanced Research Projects Agency (DARPA) is in a unique position to question
traditional sensing architectures and concepts while possessing both the charter and funding to explore and
develop the technologies necessary to accomplish both existing and desired applications. This paper describes the
logical flow from the need for long-term tracking of an extremely large number of vehicles in an urban
environment, through the fundamental requirements and the application to the phenomenology tradespace.
This paper reviews recent and ongoing antenna technology and systems development in the Special Projects Office of the Defense Advanced Research Projects Agency (DARPA/SPO). These programs fall into two categories: development and application of antenna component technologies and development of transportable phased-array radar antennas. These development programs are presented in a chronological order.
