This article analyzes the possibilities of the existing system of air intelligence of the enemy in connections and associations of ASF (ASD). Designated problem that when applying the cruise missiles significantly increased the possibility of enemy aircraft on drawing the sudden impact on objects of strategic nuclear forces and the highest levels of management. Showing alternatives to enemy air reconnaissance systems, to increase the possibility of detection of cruise missiles existing information by means of a system of  ASD. Proposed improved detection method based on spectral analysis of signals received from objectives through radar and rear-illuminated tracing enables you to detect and classify targets like cruise missiles.  Graphic dependences are analysed accuracy characteristics of measured parameters taken by the echo-signals from RADAR parameters on the basis of the proposed method, appreciated its advantages and disadvantages in contrast to the known (existing) provides conclusions and recommendations for use.
