To maintain strategic superiority for military and aerospace platforms, embedded systems must constantly evolve to embrace the latest technologies, counter new threats, and deal with new constraints. To meet these objectives, systems engineers must exploit new architectures that deliver effective solutions.
Strong mandates to move systems closer to the antenna are driven by the need to preserve signal integrity and minimize latency while shrinking the size and weight of the enclosures. As a result, these SFF (small form factor) systems must often be capable of withstanding extreme environmental conditions during operation, forcing designers to develop new packaging and thermal management techniques to overcome these tough requirements.
Because of the many different applications and installation platforms, each SFF enclosure must conform to a unique set of SWaP constraints. As a result, SFF system vendors now address these requirements with an extensive array of enclosures, which are often not compatible with open-standard system architectures.
Microwaves & RF magazine recently presented a TechXchange interview in which Ken Hermanny and Rodger Hosking of Mercury Systems discussed the technology synergies between Mercury and its recent acquisition, Pentek, and how the Sensors Open System Architecture (SOSA) fits into Mercury's future.
Product Focus: 8-Channel Phase Coherent RF Signal Recorder Extends Recording Capability for Beamforming and Radar Applications
The Talon Model RTR 2628 is an 8-channel, phase coherent, 4U 19-inch rackmount recorder with integrated RF tuners and A/D converters. The rugged rackmount system is designed to operate under conditions of vibration and extended operating temperatures. The Talon RTR 2628 accepts signals from eight antennas to provide eight channels of phase-coherent RF signal recording. Each channel is tunable up to 6 GHz and captures up to 80 MHz of instantaneous bandwidth.
Each input channel includes a 250 MHz 16-bit A/D and an FPGA-based digital downconverter with programmable decimations from 2 to 65536 for instantaneous bandwidths from 80 MHz down to 3 kHz. RF signals up to 6 GHz in frequency can be tuned, sampled, digitally-downconverted, and streamed to disk in real-time at sustained aggregate recording rates up to 3.2 GB/sec. RF tuning frequencies, A/D sampling rates, DDC decimations, and trigger settings are among the selectable system parameters, providing a system that is flexible, yet simple to configure and operate.
Xilinx and Mercury are working together to deliver up to 20× more processing power closer to the edge. View this recent webinar, moderated by John McHale, Editorial Director of Military Embedded Systems, to learn more about:
The Open Group Sensor Open System Architecture (SOSA) Consortium Launches New Technical Standard for SOSA™ Reference Architecture, Edition 1.0
The SOSA™ Consortium aims to create a common framework for transitioning sensor systems to an open systems architecture, based on key interfaces and open standards established by industry-government consensus. The open architecture supports airborne, subsurface, surface, ground, and space. The goal of The Open Group SOSA Consortium is to reduce development and integration costs and reduce time to field new sensor capabilities.
This Model 8256 development platform consists of:
