AGILENT Technologies is holding an Aerospace and Defence Symposium in Canberra and Adelaide next week.

The symposium will be held in Canberra on Wednesday, May 10, at Rydges Lakeside, London Circuit, and in Adelaide on Friday, May 12, at Sfera's on the Park, 191 Reservoir Road, Modbury.

Why is this event important?

Engineers working in military communications, radar systems and satellite communications must keep pace with rapid advances in technology while meeting unique system design and test challenges. At this event you will hear technical presentations on how to optimise test & measurement solutions for A/D applications and experience hands on demonstrations of Agilent's latest products. Understand how recent advances in test technology and new approaches to test methodology can help deliver cost effective measurement solutions that provide greater speed, accuracy and repeatability - meeting both today's and tomorrow's advanced test requirements.

What to expect

This informative symposium - focused primarily at military communications and radar systems with some applicability to satellite communications - will discuss measurement theory, test challenges and recent technology innovations. A product fair will be held throughout the day where you can see solution demonstrations for A/D applications. You are invited to attend all or some of the papers and to meet with Agilent experts during the product fair and breaks between papers. Lunch will be provided. Attendees will receive a CD ROM containing all technical presentations and other useful application information.

Who should attend?

This symposium is valuable for technicians, engineers and engineering managers responsible for the design, test and support of military communications or radar systems, subsystems and their components. A basic understanding of spectrum analysis, signal generation and transceiver/receiver design is assumed.

Paper Abstracts

Adopting an LXI Instrumentation Platform

Test systems of the future are moving to the latest platform: LXI. This new platform easily accommodates smaller form factors and a modular approach to system design, using LAN as an extremely stable, low cost backbone. This paper discusses what options are available for moving to an LXI platform. Existing LXI instruments are discussed and how they could be used to replace VXI and/or PXI instrumentation, as well as the overall benefits of the LXI platform in the aerospace/defence community.

A Design-to-Test Flow: Addressing Custom Signal Needs for Aerospace/Defence Applications

This paper addresses the challenges of creating and analysing custom signals for aerospace/defence design and test applications. A design-to-test flow will be presented and verification methods will be used to confirm system performance at each step. Finally a complete radar system simulation will be demonstrated that integrates signal sources, system models, measured hardware, circuit elements and MATLAB(r) into one simulation. It will also demonstrate the effects of interference from a co-located, HDL generated, satellite communications uplink site. Once the design phase is complete, the signal source and analysis capability in the design solution are leveraged in the testing phase to provide a custom software-defined test solution.

New Challenges for the Military Drives New Capabilities in Signal Generation

Over the last 15 years there have been dramatic changes in the types of threats encountered by the military as well as intelligence agencies. These changes have redirected defence and intelligence budgets to the development of ELINT (electronic intelligence) and countermeasure systems that can address the new threats directly. This in turn has prompted changes in the requirements for simulation of the signal environment. This paper reviews these new threats and how these signal simulation challenges can be met.

Cost-efficient Military Automated Test Systems (ATS) using Synthetic Instruments

There have been many generations of automatic test systems over the past 30+ years, each one adding increased capability and performance. However, retrofitting new instruments into legacy ATS has become an increasingly large burden for Defence. This presentation will highlight the aerospace/defence industry trends and drivers and outline the benefits and limitations of adopting a synthetic instrument architecture. The trade-offs made by instrument designers and system integrators will also be discussed.

Measurement Techniques for Wideband Radar Systems

Modern radar systems are increasingly making use of digital baseband signals, digital IF processing (DSP) and FPGA's. During this presentation we will review the tools and techniques that can be applied to make high integrity measurements including:

* Radar time domain measurements; pulse parameters, jitter and carrier's initial phase measurements,

* Radar vector analysis, chirp pulse compression, barker code pulse compression and MTI

* Radar receiver, amplifier measurement and FPGA debug.

Millimeter Wave Scalar Stimulus Response up to 325 GHz

Millimeter wave frequencies from 30 to 300 GHz are of great interest for secure communications, transportation, scientific research and homeland security. In this paper a novel mixer based scalar stimulus response (MSSR) system is described. The millimeter wave stimulus signal is generated using a multiplier and microwave synthesiser. The response is down converted to an intermediate frequency (IF) and displayed on a microwave spectrum analyser. The signal generator power and frequency are controlled by the spectrum analyser. The system can be configured to cover the complete waveguide (WG) band upto 325 GHz.
