A balloon-borne radar reflector which is to be used as a reference target for the measurement of radar echoes and also as an aid in the maintenance of radar systems has been designed, developed and satisfactorily demonstrated at the Naval Research Laboratory. The reflector, a metalized fabric balloon cover 31-12 inches in diameter, gives a great circle cross section of one-half square meter. It retains its size and sphericity regardless of altitude and thus provides an echo which is reasonably constant and uniform in all directions. Good optical qualities are incorporated into the target to aid in acquiring track. The rate of ascent can be controlled within reasonable limits. The primary frequency for which the reflector is to be used is X-Band. Range data on twelve-, nine-, six-, and four-inch diameter spheres indicates a possibility of using these sizes but further development work is required to produce them economically. Author
