In High Frequency (HF) radar system, the classic platforms for signal processing are DSP and FPGA. However, the cost of these two platforms is very high and the scalability for these two platforms is bad. So it is imperative to find a new way for HF radar signal processing. Inspired by the Software-Defined Radar (SDR) concept and remarkable hardware acceleration which is performed in the Graphics...
In HF (high frequency) radar, the discontinuous spectrum is a key obstacle for the range resolution enhancement because of the bandwidth limitation. For increasing the signal effective bandwidth as much as possible, the sparse stepped frequency signal is emerged. However, the conventional correlation processing method for this signal will produce high sidelobe, this paper proposes CS-CORR method and...
Suffering from multiform time-variant and fluctuant clutter in High Frequency Radar (HFR), uniform target detection, tracking and clutter mitigation methods will result in false alarm or missing alarm. To select optimized detection and clutter mitigation method in the region of interesting, a method maximizing the separability of the resultant classes in amplitude of range-Doppler map is used for...
MIMO radar is a new concept in which radar employs multiple waveforms to improve its performance. The paper focuses on MCPC signal application in MIMO radar, and analyzes MCPC signal performance in MIMO high frequency radar system. In this paper we introduces MCPC signal structure and the information extract, and then plots MIMO high frequency radar position and velocity ambiguity function under different...
When targets fall in different types of clutter and noise background in High Frequency Surface Wave Radar (HFSWR), uniform detection algorithms always result in poor detection and tracking performances. To solve the problem, two methods are proposed in this paper by extracting the background features according to the probability distribution and the image characteristic of the spectrum map. The first...
