A real-time radar environment simulation
Abstract
An approach to radar development and testing using real-time signal simulation was developed and successfully demonstrated in the development of a major phased-array radar system. The concept makes use of a real-time Radar Environment Simulation System (RESS) to serve as a test bed for the development and test of the host radar. The RESS generates target and clutter environment signal returns for insertion into the radar front-end video signal stream. The main feature of the RESS concept is its direct application of realistic target and clutter models to radar testing. Complex environmental models are used in an off-line general purpose computer to generate signal control tapes, which are used in an on-line, real-time signal simulation unit. The on-line system is interactive with the radar, i.e., it generates signal modulations due to beam scanning and transmitted waveform in realtime on cue from the radar transmission. Target characteristics which are reflected in the RESS outputs signals include detailed prescribed trajectories and RCS fluctuation models. Over 100 independent targets can be generated thus simulating a highly complex test environment. Clutter properties include spectral shapes, amplitude fluctuation, and spacial non-homogenities. Clutter types include ground, rain, and false targets.
