Converging Technologies and Standards Address Challenges of Modern Electronic Warfare and Radar
|
By Chris Miller, Keysight Technologies
Whether the mission is to intercept and collect, analyze or counter the many wireless signals that crowd the electromagnetic spectrum (EMS), a combination of new technology trends is increasing the probability of earlier detection, assessment, and response. The EMS on an electronic battlefield is chaotic and complex. The ability to fully understand signal behavior in a real-world environment is crucial in the design and validation of the latest radar, EW and SIGINT systems.
Let's take a look at a simple example of the current deployed state. When an aircraft detects a radar signal, it goes to its EW system's look-up table. Assuming it can identify the signal, the aircraft or an adjacent one in this case, would correspondingly select an appropriate countermeasure signal to jam it.

ODI Optics are Fast, but the VRT Packet Structure is also Impressive
|
By Larry Desjardin, Modular Methods
In October of 2017, the AXIe Consortium, the VITA trade organization, and six companies announced a new standard called the Optical Data Interface, or ODI for short. Based on optical links between instruments, instead of electrical links, ODI can stream data up to 20 GBytes/s from a single optical port, with speeds up to 80 GBytes/s through port aggegation. ODI is designed to address challenging applications in 5G communications, mil/aero systems, high-speed data acquisition, embedded systems, and communication research. A good overview of the physical characteristics of this optical interface standard, and the markets it addresses, can be found here.
ODI links, being a separate pluggable interface, can be placed on any product regardless of form factor. Below is a diagram of a hypothetical recording and playback system that combines any combination of bench instrumentation, AXIe modular instrumentation, and PXI modular instrumentation.

A Data Recorder Is Really a Time Machine
|
By Phil Brunelle, Conduant
It's not a DeLorean, a Tunnel, or a British phone booth but a data recorder is a time machine. Most people don't realize it, but they actually use time machines every day. They come in all different flavors. Most time machines are consumer-oriented and exist in the form of cameras, voice mail, and video recorders.
Each of the recordings created by these devices represents an instance, or a period of time, and place in the past. A photo represents a single instance while a video or voicemail represents an event that spans a period of time. When people review these recordings, they are looking back in time.
