FMCW Radar Analysis

The Keysight 89600 VSA software is a comprehensive set of tools for signal demodulation, vector signal analysis and time domain analysis. Option BHP for Frequency Modulated Continuous Wave (FMCW) radar analysis helps R&D and design verification test engineers quickly and easily make automated modulation quality measurements on multi-chirp linear FM signals according the evolving requirements for radar sensor performance and detection techniques in automotive, aerospace and defense applications. The new 89601B-BHP FMCW option provides signal synchronization, quick access to multiple FMCW modulation domain result traces, metrics, statistics, histograms and trend lines. 89600 VSA software with Option BHP provides design engineers more insight into and confidence in product design and quality in a shorter test time and accelerates time to market.

FMCW radar technology

FMCW is common in radar applications and is typically used for determining the distance and speed of target objects. For example, automotive companies are developing FMCW radar components, antennas, and sensors for use in adaptive cruise control (ACC), blind spot monitoring, traffic alerts, and even automated driving. These applications are at frequencies of 24 GHz, 77 GHz, and 79 GHz, with wider bandwidths of up to 2 GHz. Other radar applications such as high resolution image radar, weather monitoring radar, and ground surveillance radar use FMCW signals as well.

Scalable Measurements Across Various Hardware Platforms

The 89600 VSA software is supported by over 40 Keysight measurement platforms at analog and digital baseband, IF, RF and mmWave, so you can select the appropriate hardware necessary to acquire signal data and meet your performance requirements and test margins. To meet the wide bandwidth requirements of FMCW radar analysis, Keysight’s UXA X-Series signal analyzers can offer the highest performance signal analysis capability, with the greatest dynamic range with up to 510 MHz analysis bandwidth. The Keysight Infiniium oscilloscopes and M9703A AXIe wideband digitizers are the ideal solution for even wider bandwidths.

FMCW radar analysis in spectrum and time domains

Keysight 89600 VSA software has various analysis capabilities for measuring signal quality and troubleshooting problems with its standard vector analysis and optional modulation analysis. FMCW radar sensor testing can be performed using basic vector analysis in frequency and time domains. Therefore, using the 89600 VSA software with Option BHP to verify measured time, reference and error traces for amplitude, phase, frequency (FM), and FM slope offers an easy way to visually compare multiple linear FM chirps with customized traces.

Statistical linear FM analysis

To capture unknown signal errors, irregular events, or intermittent signal events introducing risks to system design integrity, it is essential to use the appropriate analysis and diagnostic tools to record long time samples and monitor trends. Statistical analysis tools provide more insight into your FMCW system with views of various parameters.
