Estimation Techniques for Far-field Exposure Contributions

The model using two structure attenuation coefficients was used to estimate the far-field exposure contribution for an experimental house. Restricted least-squares and minimum absolute deviation (MAD) techniques were used to make these far-field exposure contribution estimates. The latter two methods yielded results which were superior to the usual unrestricted least-squares technique. The far-field contribution was always positive and all coefficients were positive but less than unity.
