FMCW Radar Measurement Basics

The basic computation for FMCW Radar Analysis consists of:

1. Automatically identify valid Linear FM Frequency Modulation region locations within the Acquisition Time trace based on user specified FMCW Reference Region Synchronization parameter settings
2. For each detected region, provide synchronized time aligned trace results for:
   • Measured trace data Amplitude, Phase, FM and FM Slope
   • Reference trace data, Phase, FM and FM Slope
   • Error trace data, Phase, FM and FM Slope
3. For each detected region, provide tabular performance metrics within:
   • Region Table
4. Accumulate statistical performance metrics within:
   • Current Record Statistics
   • Cumulative Statistics
5. Generate graphical visualizations of statistical performance metrics within:
   • Trend Lines
   • Histograms

 

Data Acquisition

The FMCW Radar Analysis measurement supports data acquisition from all existing Keysight 89600 VSA Software supported front-end hardware instruments, within the RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). frequency, span, and memory capture limitations of that hardware instrument and 89600 VSA Software data acquisition interface.

The FMCW Radar Analysis measurement allows individual signal acquisitions long enough to contain many regions.

The signal being analyzed may come from an external down converter, in which case the VSA Software’s external down converter feature can be used to ensure that traces and results have correct frequency labeling.
