Research of the possibility of increasing the uniqueness of determining the time delay of the phase-code shift keyed signal in a correlation meter on the basis of FPGA
Background.In radar systems, phase code-domain keying signals are widely used.Continuous signals of this kind have the advantage of low side lobes of the cross-correlation COFFEEBERRY function and high noise immunity, but have limitations on the size of the area of view associated with the presence of ambiguity peaks.Aim.The paper considers the pos
