Abstract:

A planned procedure is described for testing 3.5 GHz environmental sensing capability (ESC) devices for their responses to radar pulses in a laboratory environment. These test procedures will be used to gather data on ESC pulse-detection performance. The data gathered via these procedures will be provided to the Federal Communications Commission (FCC) to support that agency’s certification process for eventual ESC field operations. This document is the best guideline for ESC laboratory testing that can be compiled by the government at the time of publication. This document is not necessarily comprehensive regarding all testing that ultimately may or should ever be performed on any ESC system. Technical procedures and approaches described in this report may be deleted, expanded, or otherwise modified in the future as experience is gained with ESCs. Such changes would be based on inputs from industry and government agency stakeholders, and on contingencies that may arise from changes in future ESC certification requirements and in the designs of future ESC systems. However, no near-term change to the described testing procedures or radar signal parameters for ESCs as given in this document is expected.

Additional ESC certification test tasking identified after this memo was published is described in Frank H. Sanders; Robert L. Sole; Geoffrey A. Sanders; John E. Carroll, "Further Procedures for Laboratory Testing of Environmental Sensing Capability Sensor Devices," NTIA Technical Memo TM-18-534, June 2018.To provide all the data required for the FCC certification process, both the procedures described in this memorandum and the procedures described in TM-18-534 must be followed.
