ALGORITHM FOR SYNTHESIZING VIRTUAL ANTENNA ARRAY APERTURE BY EXTRAPOLATING THE APERTURE FUNCTION BASED ON SEQUENTIAL SIGNAL PROCESSING
Annotation
The ways of increasing a radar station detecting ability are analyzed and a promising software and hardware architecture are presented. As an original solution, a principle of synthesizing a virtual aperture is substantiated. The principle is based on extrapolation of the antenna array aperture function as applied to solving the problem of detecting stationary objects in condition of reliable background and target setting. The algorithm for virtual aperture synthesizing is considered in detail and a variant of its implementation is described. The main calculation ratios are formulated, and simulation data are presented.
