“…As the space is limited, we only consider the influence of the first-order sea clutter and treat the second-order and high-order sea clutters as the noise in this paper. It is known that in pulse-Doppler HFSWR systems most of the targets and sea clutters can be separated by their distances and relative velocities via range and Doppler transforms [5]. For a given resolution cell of range and Doppler, therefore, only a small number of sources need to be estimated.…”

By exploiting the intrinsic sparsity of the spatial spectrum for a given resolution cell of range and Doppler, this study introduces the recently developed sparse representation approaches for direction-of-arrival estimation in shipborne high-frequency surface wave radar (HFSWR). These approaches can reconstruct the sparse signal and obtain highresolution spatial spectrum with a small number of snapshots or even single snapshot. A generalised real-valued sparse representation, which seeks to replace the complex-valued problem with a real one, is proposed to reduce the computational complexity and improve the resolution probability and the estimation accuracy. The advantage of the proposed method is demonstrated by theoretical analysis and numeral simulations. Furthermore, validation of the proposed method is verified by the experiment of shipborne HFSWR on the Yellow Sea of China.

“…In general, the antenna array of high-frequency ground wave radar (HF GWR) is located near the seashore [4,5] , so it is expensive and inconvenient to calibrate the array with auxiliary sources. In this case, the appropriate method is the self-calibration.…”

According to the characteristic of the echo of highfrequency ground wave radar(HF GWR), which is one-dimensional narrow band signal, a virtual direction of arrival(DOA) matrix is constructed at first, then the DOA of target evaluation is achieved by the method of resolving equations for two-dimensional DOA matrix. And this method bases on the redundancy information of a linear two-row array of antennae. Both the simulation process and the treatment results of measured data (in the case of low SNR echoes and short data series) are given at the end of this paper. By comparing with GPS data of the targets, the validity and practical applicability of the method in this paper is verified.

“…High frequency surface wave radar (HFSWR) is a promising technology for lowcost, all-weather, accurate and reliable surveillance for both remote sensing of the sea surface [9] and detection of surface vessels and low-flying aircraft well in excess of the visible horizon [6]. When designing an HFSWR receiver, there exists a great demand for high integration and portability and for meeting the consumer demand for low cost and small size.…”

This paper studies the design and multiplierless realization of a digital down converter (DDC) in a high frequency (HF) radar receiver. The novel structure mainly consists of a fast Walsh transform (FWT) and an inverse fast Walsh transform (IFWT), both of which can be implemented using only addition and subtraction. Because the transform kernels of the FWT and the IFWT are the same, the implementation complexity of the DDC is significantly reduced. Simulation and field test results are given to demonstrate that the proposed method outperforms the common method and is suited for real-time signal processing of software digital down conversion in a digital signal processor (DSP), such as the ADSP21060.
