This paper proposes a deployment for sparse array in motion and analyzes the estimation performance of the arrival angles. The background of the system model is in underwater environment and the sensors are considered as passive sonars. In order to minimize the number of physical sensors, an algorithm based on space-domain sensor synthesis (SDS) is proposed. Considering the phase shift in the signal,...
In this paper, we propose a Time Difference of Arrival (TDoA) algorithm for passive geolocation based on delay estimation of two correlated wireless channels. It's assumed that the passive receiver is carried by a small flying UAV in the sky, and the transmitter is located on the ground (static or mobile), so Rician flat fading model should be used. To estimate the delay of two correlated channels,...
In this paper, we present new developed ternary code - punctured binary sequence-pair, give its definitions and the autocorrelation properties. We also investigate Doppler shift performance of the proposed code. The significant advantages of this ternary codes over conventional pulse compression codes, such as the widely used Barker codes, are zero autocorrelation sidelobes and the longer length of...
Based on the zero correlation zone (ZCZ) concept, we present the definition and properties of a set of new triphase coded waveforms -ZCZ sequence-pair set (ZCZPS) in this paper and propose a method to use the optimized punctured sequence-pair along with Hadamard matrix construct the optimized punctured ZCZ sequence-pair set (optimized punctured ZCZPS). According to property analysis under the Doppler...
