NTIA Seal Radio Spectrum Measurement System (RSMS) Program
RSMS Radar Data Collection:

Because of some unique problems posed by the measurement of radar signals, a particularly large effort has been applied to measurement algorithms and custom-designed RF hardware to accurately and efficiently characterize such signals. The resulting solution allows the RSMS to measure radar signals with the following capabilities:
  • 120 dB dynamic range;
  • full frequency range of emission spectrum occurring within the dynamic range listed above;
  • antenna patterns with multipath features automatically removed;
  • beam scanning patterns characterized rapidly;
  • pulse sequences characterized rapidly.
Examples of radar emission spectra measured by the RSMS can be found in NTIA Report 82-92, Output Tube Emission Characteristics of Operational Radars, Matheson, et al., January 1982.
