On October 27, 2022, the U.S. Department of Defense publicly released the unclassified National Defense Strategy (NDS), a Congressionally-mandated review. This strategy sets the strategic direction of the Department to support U.S. national security priorities and flows directly from President Biden’s National Security Strategy. The NDS includes the Nuclear Posture Review (NPR) and the Missile…
The DSIAC Journal is a publication of the Defense Systems Information Analysis Center (DSIAC). DSIAC is a DoD Information Analysis Center (IAC) sponsored by the Defense Technical Information Center (DTIC) with policy oversight provided by the Office of the Under Secretary of Defense (OUSD) for Research and Engineering (R&E). DSIAC is operated by the SURVICE Engineering Company.

Introduction Polyetheretherketone (PEEK) is a semicrystalline thermoplastic that was invented in November 1978 and brought to market in 1981 by Imperial Chemical Industries, which later became Victrex. As developed, this material possessed a maximum 48% degree of crystallinity. The composite material was introduced a year later as APC-1 with a 52% fiber volume, and it was optimized to yield APC-2 with a 63% fiber volume….

Summary Anomaly detection, whereby signals are scanned for behavior changes, is a common problem in many applications. As data streams grow in complexity and volume, automated methods for anomaly detection, especially those based on machine learning (ML), are increasingly attractive. However, many real-world defense applications like space domain awareness (SDA) are challenging environments for these algorithms because sensors can be noisy, datasets can be large,…

Summary This article describes research to detect phenomena that may degrade or disrupt the performance of an otherwise fully functional sensor. Also examined are methods to potentially mitigate the effects of sensor degradation and develop effective countermeasures that enable naval vessels and unmanned vehicles to continue their missions with degraded capabilities. An emphasis is placed on protecting sensors and sensor systems from cyberattacks and physical…

Summary Autonomously detecting tiny, fast-moving objects emitting thermal radiation in the infrared is a challenging technical problem. In addition to being fast, these targets are often dim, small, and in the presence of clutter and occlusions. Conventional detection approaches require large size, weight, and power (SWaP) systems which may introduce substantial latencies. As such, the following will be explored in this article: An end-to-end system…

Summary Emerging technologies include not only novel technical inventions but also repurposing existing technologies into new tactics, techniques, and procedures. In recent years, Russia and China have upended the way the space domain has operated for decades. For example, China has repurposed the Cold War-era concept of a “fractional orbital bombardment system” to deploy a novel hypersonic vehicle. Russia has deployed a test satellite in…
