RF Transceivers Enable Forced Spurious Decorrelation in Digital Beamforming Phased Arrays

In this paper we review a previously published technique to force spurious signals to be uncorrelated by offsetting the LO frequencies and digitally compensating for this offset. We then show how the most recent Analog Devices transceiver product, the ADRV9009, has built in features enabling this capability. We then conclude with measured data demonstrating the results of the technique.

Raytheon Delivers First SeeMe Satellite to DARPA

Small satellites will increase situational awareness for ground troops

Raytheon Company has delivered the first Space Enabled Effects for Military Engagements, or SeeMe, satellite to DARPA. Assembled on the company's advanced missile production lines, the new SeeMe satellite will provide greater situational awareness to soldiers on the ground. DARPA's SeeMe program is designed to show that small satellites can be built affordably to give small squads timely tactical imagery directly from a small satellite.
