FM Radio Reception Simulation in Open Space 2002-01-0121

A new method to simulate “the FM radio reception on the road” in an open space is proposed. It can provide reliable and objective evaluation of the radio system including a vehicle. It can reduce the cost and time of the driving test on roads. It is based on two technologies. One is a wave-extraction system of incoming waves on the roads and the other the field reconstruction in an open space. For the extraction, 3-D software based on AIC is developed and can estimate the number of waves and the amplitude, phase and polarization of the waves from the field data. The software showed the extraction accuracy of 90% in simulation. This method was applied to the road test, and it was found that the software could extract the waves. And through several tests in the space, the feasibility of the reconstruction of standing wave was confirmed (Maximum-minimum ratio: 18 dB and 22 dB at FM-band for the horizontal and the vertical polarization).
