A new pulse compression technique generating optimal uniform range sidelobe and reducing integrated sidelobe level

Abstract

A novel pulse compression technique is developed that produces an optimal uniform range sidelobe of the ideal Barker code level. The newly obtained sidelobe pattern provides an optimal compromise between the range resolution and the peak sidelobe level (PSL), regardless of the signal code length, and also retains the merit of strong resistance to the Doppler shift effect. Very low sidelobe regions appear around the mainlobe peak, which is useful in target tracking and recognition. A novel processing technique is proposed to reduce the ISL energy. A sidelobe canceller is generated directly from the incoming signal and combined together with the original pulse compression output in which unwanted sidelobes are significantly eliminated.
