High Resolution MIMO-HFSWR Radar Using Sparse Frequency Waveforms
In high frequency surface wave radar (HFSWR) applications, range and azimuth resolutions are usually limited by the bandwidth of waveforms and the physical dimension of the radar aperture, respectively. In this paper, we propose a concept of multiple-input multiple-output (MIMO) HFSWR system with widely separated antennas transmitting and receiving sparse frequency waveforms. The proposed syste...
متن کاملSparse Frequency Waveform Design for Mimo Radar
Multiple-input multiple-output (MIMO) radar has superior performance to conventional one. It has been introduced to almost every application field of conventional radar in recent years. In practical application, MIMO radar also faces the problem of congested spectrum assignment, which makes it not possible to have a continuous clear band with large bandwidth. Sparse frequency waveform that cont...
متن کاملIonosphere Probing with a High Frequency Surface Wave Radar
This paper describes how the ionosphere reflected echoes observed by a high frequency surface wave radar (HFSWR) can be processed to extract information regarding the ionosphere sporadic E (Es) and F2 layers. It is shown that the range/time spectrum contains the data to estimate the occurring time and virtual heights of both the still and drifting Es layer clouds. In addition, for the drifting ...
متن کاملDetection Performance Improvement of FMCW Radar Using Frequency Shift
Frequency modulated continuous wave (FMCW) radars have been widely used for measuring target range and speed. In this paper, we present a mathematical model that quantifies the system-level performance of FMCW radar systems. In FMCW radar, the target range is measured through measuring the beat frequency between the transmitted and received signal, usually by using Fast Fourier Transform (FFT)....
متن کاملFmcw Based Mimo Imaging Radar
There are a number of potential applications for low cost short range phased array radar sensors: ship bumpers, large vehicle sensors and level crossing obstacle detection for example. Phased arrays have the benefit of reduced size and the elimination of moving parts compared with more traditional rotating antenna systems. Another potential benefit is that the image update rate can be orders of...
