wrt ae fs This involves detection and identification of nuclear explosions carried out in the following physical environments. 4 { a Vere, ea 1, At the Earth's Surface and at Low Altitudes within the USSR and China. It would be feasible to detect and identify explosions at the .earth's surface and at low altitudes, having yields down to about: ‘| riistsss with the net of seismic, acoustic and electromagnetic stations “located within the USSR and China, described in Appendix A. Positive identification requires the collection of nuclear debris which may in some cases involve overflight of the USSR or China. 2. At Very High Altitudes Over the USSR and China. Electro- magnetic detection techniques, based on theoretical predictions, show OE ee ey ee thet ee Re great promise of detecting and identifying nuclear explosions created at very high altitudes. This is discussed in detail in Appendix B. A close net of some :1 }electromagnetic detection stations would suffice, subject to confirmation of actual capabilities. Earth satellites could carry instrumentation for detecting and identifying the nature and location of nuclear detonations both within and outside the earth's atmosphere. 3. Below the Earth's Surface. Nuclear explosions conducted well below the earth's surface are mostdifficult to detect.
