Realistic Radar Target Augmentation.
Abstract
This report presents the results of a program to enhance the radar reflectivity pattern characteristics of a self-propelled high altitude target system (HAST). An analytical review of the characteristics of aircraft radar scattering cross-section and the resultant effects on weapon systems is presented. A target system that would permit a realistic weapon test is shown in block diagram. Important weapon system parameters are analyzed and discussed under assumed conditions which are derived from a detailed literature search. Desired target characteristics are defined on the basis of Government-supplied data on the equivalent scattering cross-section of the target to be simulated. Active radar augmentation devices comprise the design approach and a block diagram is shown. Antenna placement and angular pattern coverage are pictorially presented. The conclusion is that theoretically the approach is reasonable and can be attained in either a single traveling wave tube or in a cascaded pair. The hardware implementation phase defines problem area and attempts made to correct performance deficiencies. Sixteen-element spiral antenna arrays deteriorated in performance in both pattern shape and peak gain as a function of time. Repeated attempts to obtain the required overall system gain were less than desired. (Author)
