Patent ID: 8531343

Claim:
An electromagnetic environment simulation method comprising: placing a wireless system under test in an antenna measurement facility having a probe antenna and a positioner; programming said positioner with a predetermined solid angle scan; programming said probe antenna to transmit an electromagnetic signal ψ n corresponding to its position relative to the wireless system under test in the predetermined solid angle scan φ n ; transmitting from said probe antenna an initial electromagnetic signal ψ 1 corresponding to its position relative to the wireless system under test in the solid angle scan φ 1 ; recording in the time domain without demodulating, at a high dynamic range resolution, the signal χ 1 received by said wireless system under test; moving said positioner to the next sequence in the solid angle scan; transmitting from said probe antenna a non-initial electromagnetic signal ψ n corresponding to its position relative to the wireless system under test φ n in the solid angle scan; recording in the time domain without demodulating, at a high dynamic range resolution, the signal χ n received by said wireless system under test; iterating through said moving said positioner to the next sequence in the solid angle scan, transmitting from said probe antenna said non-initial electromagnetic signal ψ n corresponding to its position relative to the wireless system under test φ n in the solid angle scan, and recording the signal χ n received by said wireless system under test steps until the entire predetermined solid angle scan is completed; and combining by superposition in the time domain the signals χ n .
