Technology Development and the Need for Realistic Testing under Realistic Conditions
President, Sensor Concepts & Applications, Inc.
In support of, and through funding from, DNDO, we have developed a capability to simulate the key operational environment for the detection of nuclear material under a wide variety of simulated real world conditions. Additionally, the ability to collect data from prototype systems and to analyze the data collected in such a way that performance information can be fed back to the vendors has proven critical in the advancement of these technologies.
The rigor applied to testing at DNDO includes the ability to explore real and simulated threat objects, operational conditions such as conveyances and contents (e.g., cargo) of conveyances, more controlled test condition such as ANSI standard benchmarks, and a Data Collection, and Analysis and Management (DCAMS) software system that insures documentation, quality control and quick turn-around of results. The DCAMS has been used in a variety of ways from very formal double blind testing to informal investigations of many settings and system thresholds during the later stages of system development.
DNDO has created methods of reusing data collected to stimulate algorithm improvements by sequestering portions of the data and releasing to the developer other portions of the data for improving results. This replay of the data has been shown to be effective in improving system capability.
In this presentation, we will describe the complexity and robustness of the TAR Technology Demonstration and Characterization campaigns as well as present the opportunities for simulating operational environments.
