Based on space-borne multiple-input single-output radar systems, a novel orthogonal bi-phase coding waveform optimization design method is presented. However, it is impossible to design a set of codes with ideal impulsive autocorrelation and idea zero cross-correlation performances. Hence, only the shape of its main-lobe and side-lobe near the detected range cell is considered as the optimization criteria. The aperiodic correlation properties are discussed. Simulation results show that the proposed algorithm is effective and feasible.

An adaptive beamforming method for ultrawide-band (UWB) array in the case of nearfield is proposed based on the radical basis function neural network (RBFNN) in this paper. The desired outputs corresponding with measured inputs for the nearfield impulse source are reflected into a set of training samples. Genetic algorithm and recursive least square algorithm are employed to determine the structure and the parameters of RBFNN. It can avoid the computation of an inverse matrix and alleviate the impact of the mutual coupling phenomenon. The experimental results also prove its efficiency and feasibility.
A heterogeneous Markov chain (MC) model, instead of the homogeneous MC model, is proposed in this paper to describe target existence variable for Bayesian track-before-detect. The proposed model is more consistent wit...

Blind signal extraction(BSE) is an efficient way to recover the source signals from the observed signals. In this paper,a new adaptive algorithm of blind signal extraction based on the skewness was introduced for the signals whose probability distribution is not *** algorithm cooperated with the deflation procedure realizes the extraction of source signals one bye *** third-order statistics are used in the novel algorithm,so it can reduce the computational burden *** simulations confirm the validity and performance of the algorithm.
The ability of MIMO InSAR to reconstruct the terrain height profile would outperform the ordinary multibaseline InSAR. One key of implementing MIMO InSAR is the echo separation on the receiving end. However, the avail...
