In this paper, a novel design scheme for radar signal is proposed. It is based on a modification of Costas codes design obtained by increasing the frequency separation of frequency hops beyond the orthogonality condition. This condition states that frequency separation between frequency hops should be at most equal to the inverse of bit duration of the code. Indeed, increasing frequency separation...
In maritime and aeronautical transports, intelligent systems such as AIS2AIS – Automatic Identification System. 2 or ADS-B3ADB-S – Automatic Dependent System-Broadcast. 3 are used for simultaneous location and data exchange. However nowadays, in guided transports domain, no commercial system is able to ensure the both functionalities. In this paper, we present the achievement of an...
