Abstract

Abstract:

In order to solve the problems of “large position, difficulty with location chosen, low angle resolution, and poor flexibility”, and to improve the performance of DOA estimation, a new design of the distributed high frequency surface wave radar is proposed, based on the technology of distributed antennas array and the MIMO radar system. With the new design, we propose a new DOA estimation method using compressed sensing, this method reduces the complexity of data processing and solves the angle ambiguity due to the distributed array. Discrete stochastic and semi-QR factorization is also used for improving the performance of the new DOA estimation. Theoretical analysis and simulation results show the validity of the proposed method.

Key words: distributed high frequency surface wave radar, compressed sensing, discrete stochastic, semi-QR factorization
