UAV Can Launch Aerial Missions from Underwater

Researchers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, have developed an innovative unmanned aerial vehicle (UAV) that can stay on station beneath the water until needed, then launch into the air to perform a variety of missions. The Corrosion Resistant Aerial Covert Unmanned Nautical System — or CRACUNS — is a submersible UAV that can be launched from a fixed position underwater, or from an unmanned underwater vehicle (UUV). A team from APL’s Force Projection Sector worked with fabrication experts in the Research and Exploratory Development Department to create a new type of unmanned vehicle that can operate effectively in two very different arenas: air and water.

Detecting Radioactive Material from a Remote Distance

In 2004 British national Dhiren Barot was arrested for conspiring to commit a public nuisance by the use of radioactive materials, among other charges. Authorities claimed that Barot had researched the production of “dirty bombs,” and planned to detonate them in New York City, Washington DC, and other cities.

Tiny UAS Could Be Warfighters’ Eyes in the Sky

The basic small-unit fighting capability of the Army is the squad. One of its weaknesses is broad-area situational awareness, particularly in unfamiliar environments, according to Col. Phil Cheatham, deputy branch chief of the Electronics and Special Developments Branch at the Maneuver Center of Excellence (MCOE), Fort Benning, Georgia. A likely solution? A nano unmanned aerial system (UAS) with reconnaissance capability called the Soldier Borne Sensor (SBS).

50 GHz Handheld Combination Analyzer

Keysight Technologies, Inc. (Santa Rosa, CA) has added six millimeter-wave models to its family of FieldFox handheld analyzers. The flagship model is the industry’s first handheld combination analyzer to provide coverage to 50 GHz. Three combination-analyzer models cover 32, 44 or 50 GHz and provide spectrum analysis, vector network analysis, and cable and antenna testing in a rugged, portable unit. The three spectrum analyzer models cover the same frequency range.

31–36 GHz Receiver

Richardson RFPD (Geneva, IL), Inc. announced the availability and full design support capabilities for a new receiver from M/A-COM Technology Solutions. The XR1020-QH is a 31–36 GHz receiver with a noise figure of 3 dB and 14 dB conversion gain. It integrates a low noise amplifier, image reject mixer and LO buffer amplifier within a fully-molded, lead-free, 4-millimeter, 24-lead PQFN package. The image reject mixer eliminates the need for a bandpass filter after the LNA to remove thermal noise at the image frequency. I and Q mixer outputs are provided, and an external 90° hybrid is required to select the desired sideband. The XR1020-QH is suitable for point-to-point radio, SATCOM and military applications.
