Northrop Grumman flight tests Digital Wideband AESA Sensor

Baltimore MD (SPX) Jun 23, 2021
Northrop Grumman Corporation has flight demonstrated its new Terracotta sensor - a fully-digital open mission systems (OMS)-compliant wideband active electronically scanned array (AESA).
The flight test was a follow-on to successful ground and flight demonstrations of Terracotta conducted last fall.
This most recent flight verified Terracotta's ability to simultaneously perform active and passive radio frequency capabilities. Terracotta's nearly 200 wideband digital channels can be molded cooperatively or segmented for unique purposes, including electronic warfare, airborne early warning radar, active and passive sensing, and communications.
"As a fully-digital multifunction sensor with a wide operating bandwidth, Terracotta can seamlessly provide adaptive spectrum maneuverability," said Paul Kalafos, vice president, surveillance and electromagnetic maneuver warfare.
"The sensor's architecture is easily scaled and configured for many applications and systems across all domains. It represents a key enabling technology for joint all domain operations."
Unlike traditional sensors, multifunction apertures consolidate multiple capabilities into a single sensor, decreasing both the number of apertures needed and the size, weight, and power requirements for the advanced capabilities. Sophisticated multifunction apertures like Terracotta can deploy several functions simultaneously.
OMS compliance offers an interface solution based on open architecture design allowing customers to rapidly add new or improved capabilities, regardless of supplier, at a reduced cost. Northrop Grumman plans to integrate a combination of OMS/Open Communication Systems sensors and software-defined radios across multiple platforms, networks and nodes to address driving mission needs and ensure multi-domain interoperability.
Radar reveals that male bees gather in certain locations to mate with queens
Washington DC (UPI) May 20, 2021
With the help of radar technology, scientists are gaining new insights into the sexual lives of honeybee drones. According to a new study, published Thursday in the journal iScience, bees gather in certain aerial locations where they attempt to intercept and mate with queen bees. Previously, scientists have observed thousands of male honeybees gathering at "drone congregation areas." But the phenomena is typically triggered by the deployment of pheromone lures, raising questions a ... read more
