ABSTRACT:
There is disclosed a method and apparatus for verifying the integrity of a smart antenna system. A signal simulator replicates the respective signals received at the multiple sensors of the antenna array, with signal parameters that include the correlated effects of Doppler, delay and angular spread. A combination of hardware and software capabilities simulate a primary line-of-sight signal, plus reflected signals and refracted signals, which requires manipulation by the smart antenna processor to extract the temporal and spatial information of the signals of interest. The simulated signals may be varied in numbers, amplitude, phase, delay and bearing components for representing a variety of terrain, environmental, equipment and capacity conditions encountered in alternative environments and conditions. The output of the smart antenna processor is checked against the input parameters to compare, verify and calibrate the smart antenna system.
