A coprime array of N sensors can achieve O ( N 2 ) degrees of freedom (DOFs) by possessing a uniform linear array segment of size O ( N 2 ) in the difference coarray. However, the structure of difference coarray is sensitive to sensor failures. Once

Radar Maneuvering Targets Tracking (RMTT) in clutter is a quite challenging issue due to the errors in the models and the varying dynamics of the processes. Modern radar tracking system calls for the adaptive signal and data processing algorithm urge

The accuracy and efficiency of the particle filter algorithm partly depend on the number of particles used in the estimation. The number of particles is specified beforehand and kept fixed in the process of radar manoeuvring target tracking (MTT). In

In this paper, to improve the utilization of noncontiguous virtual sensors of the coprime array, we propose a covariance matrix reconstruction method for underdetermined direction-of-arrival (DOA) estimation. Firstly, the distribution characteristic

The traditional algorithm of single station location are mainly for the single moving station to the fixed emmiter or the fixed station to the moving emmiter, however, it is very difficult for a moving station to bring about a fast and accurate locat

The rate of phase difference change is an important index of passive location measurement. In the actual situation, the rate of phase difference change is not large, and the phase difference will not change much in a short time. In this paper, a phas

when we estimate the DOA of LFM signal based on the traditional algorithm, it occurs many problems such as large sampled data and low estimation accuracy under low SNR. This paper proposes a new DOA estimation method based on compressed sensing theor

Modulation of the plasma current has been used successfully to suppress MHD activity. This was achieved in discharges near the density limit where large MHD m = 2 tearing modes were suppressed by sufficiently large plasma current oscillations. The mo

A new asymmetrical Abel inversion is presented for application in asymmetrical data which is obtained from plasma diagnostics on the toroidal plasma system. Asymmetry in the system exists in the direction along chord distribution. This new method is
