Abstract

One of the methods for improving maximum radar range performance is increasing the average transmitted power. In this paper, this objective is achieved by nesting binary phase coded waveforms with different lengths. The decoding of these nested codes leads to appearance of high sidelobes which are canceled by nesting corresponding optimum filters.
The hardware structure of the encoder and sidelobes cancellation processor of these nested codes are simply realized by cascading the corresponding original Barker code filters with changing the filter length in each cascaded level.
