Application Notes - measurement solution tips/techniques
- Surveying the Best Ways to Test Antennas and Antenna Arrays - In our ongoing discussion of practical test methods, we’ll now take a closer look at the testing of antennas and antenna arrays. This topic spans a variety of test setups and test methods: far-field and near-field test ranges; multi-aperture and phased-array radar systems; and radar cross-section (RCS) measurements.
- Overcoming RF & MW Interference Challenges in the Field Using Real-time Spectrum Analysis (RTSA) - Learn practical strategies to overcome RF and microwave interference challenges using RTSA. See why this type of analysis is required to troubleshoot interference in today’s aerospace defense networks with bursty and elusive signals.
- Radar Measurements Part 7: Assessing and Improving Radar System Performance - Continuing our discussion of practical test methods, we’ll now explore three ways to assess and improve radar system performance: noise figure, time sidelobe level and phase noise. Noise figure has a direct effect on receiver performance; time sidelobe level affects spatial resolution, dynamic range, and more; and phase noise causes sidebands that reduce signal-to-noise ratio. This note presents a variety of ways to measure and characterize each of these parameters.
- Radar Measurements Part 6: Surveying the Best Ways to Test Antennas and Antenna Arrays - In our ongoing discussion of practical test methods, we’ll now take a closer look at the testing of antennas and antenna arrays. This topic spans a variety of test setups and test methods: far-field and near-field test ranges; multi-aperture and phased-array radar systems; and radar cross-section (RCS) measurements.
- Radar Measurements Part 5: Characterizing Radar Components and Subassemblies - In our ongoing discussion of practical test methods, we’ll now take a closer look at the testing of components and subassemblies. The ability to maximize radar performance depends on thorough analysis and careful optimization of each component and subassembly in a radar system. Two types of instruments simplify these measurements: power meters and vector network analyzers (VNAs). We’ll take a closer look at both, but the emphasis is on the range of VNA capabilities that enable characterization of components and subsystems that carry pulse-modulated signals.
- Radar Measurements Part 4: Measuring Radar Signals with Vector Signal Analyzers and Wideband Instruments - In our ongoing discussion of practical test methods, the next step is to examine the use of vector signal analyzers (VSAs) and wideband instruments—signal analyzers and oscilloscopes—to measure the frequency and phase in today’s increasingly complex radar signals. Compared to traditional approaches that combine multiple instruments, these integrated tools provide enhanced ease of use that makes it easier to produce accurate, repeatable measurement results.
- Radar Measurements Part 3: Measuring the Characteristics of Pulsed Radar Signals - Extracting the frequency and timing characteristics of a pulsed signal opens the door to a deeper understanding of the transmitter performance. This application note, the third in the series, describes measurement alternatives that range from low-cost counters to full-featured spectrum and signal analyzers with a wealth of built-in capabilities and dedicated measurement applications for pulse analysis.
- Radar Measurements Part 2: Defining the Pulsed Radar Signal and the Essential Measurements of Signal Power – A radar transmitter is often the most costly component in a system and can have the greatest effect on system performance. This application note, the second in the series, defines the nature of actual radar signals and describes practical ways to measure the power in those signals.
- Radar Measurements Part 1: A Framework for Understanding: Deriving the Radar Range Equation - This application note is the first in a series that delves into radar systems and the associated measurement challenges and solution. In this application note, we take a closer look at the mathematical foundation for all current trends and technologies in radar: the radar range equation.
- RF Streaming for Aerospace & Defense Applications - This application note discusses how critical it is for the system engineer to not only precisely measure the time it takes for a radar warning receiver to recognize a possible threat, but also how long it takes the system to generate an appropriate response.
- Accelerating the Testing of Phased-Array Antennas and Transmit/Receive Modules - In applications as diverse as radar, radio astronomy and wireless communications, developers are using antenna arrays to enable beamforming. This technique provides many benefits.
- Using Calibration to Optimize Performance in Crucial Measurements - This application note provides tips to ensure you get the calibration you expect (and deserve), and help you improve effective measurement performance through innovative use of calibration data and results.
- Using Wider, Deeper Views of Elusive Signals to Characterize Complex Systems and Environments - looks at signal-identification techniques for monitoring EW scenarios, identifying unwanted spectral events or detecting issues in transmitted waveforms. For identified signals, the narrative discusses methods for making pulsed vector measurements in both the time and frequency domains. The second part outlines several analysis options that support typical requirements in dynamic range and bandwidth
- Pulse Analysis Techniques for Radar and EW - describes the best tools for different types of pulse analysis, along with display and analysis techniques for various signals and measurement goals. It also looks at key signal acquisition and processing technologies such as IF and frequency mask triggering, signal capture, and post-processing.
- Electronic Warfare Signal Generation: Technologies and Methods - summarizes the available technological approaches for EW signal and environment simulation, and the latest progress in flexible, high-fidelity solutions.
- Choosing the Right Emitter Generation Source for Radar/EW Applications – helps narrow down the decision making process and ensure existing assets are well utilized.
- Assembling Cost-effective Development and Verification Solutions for EW Systems – This application note presents two off-the-shelf alternatives that can address the simulation requirements of subset scenarios for a system under test (SUT). The proposed alternatives offer greater versatility because the constituent instruments can be easily used for other measurement tasks.
