L'Application des Codes de Costas et des Codes a Congruences Quadratiques a la Compression d'Impulsion Numerique (The Application of Cost, Codes and Quadratic Congruence Codes to the Compression of Numeric Impulsion)

Abstract

In this report we present the analysis and construction methods for two types of frequency coded pulses: (a) Costas codes and (b) quadratic congruential codes. These codes have the characteristic of producing a thumbtack ambiguity diagram with low sidelobes. Computer simulations were performed to calculate their autocorrelation functions. Comparative evaluation of the performance of these codes and well known codes was carried out. Results showed that Costas codes and quadratic congruential codes have low sidelobes but not as low as the chirp, step-chirp or pseudo-random codes.
