Proximity Measuring for Use in Collision Detection Systems
Paul E Tartaglia · SAE technical papers on CD-ROM/SAE technical paper series · 1974
The various methods available for proximity measuring are described and evaluated, resulting in the choice of radar as the best method available. Radar does have its drawbacks, however, and its major liability is the production of a possible health hazard in the form of microwave radiation. Limits imposed by the U.S. government are presented and compared to values obtained from a proposed system.
