Fmcw Based Mimo Imaging Radar for Maritime Navigation
The berthing of large ships in inclement weather with frequently poor visibility presents a challenge. To assist with this application, it may be beneficial to utilise standard radar imaging. Whilst this may be achieved using a mechanically-scanned system, reliability, cost and weight issues, coupled with the need to primarily image only a 120◦ sector on the port and starboard of the ship, make...
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...
متن کاملA MIMO FMCW radar approach to HFSWR
In this paper we propose one possible approach how to apply the concept of multiple-input multipleoutput (MIMO) to monostatic Frequency Modulated Continuous Wave (FMCW) High-Frequency Surface Wave Radar (HFSWR) in a maritime environment. Common tasks for a HFSWR are sea-state monitoring and ship detection, where our focus is on ship detection. A limiting factor in HFSWR is the available bandwid...
متن کاملBroadband Millimeter-wave FMCW Radar for Imaging of Humans
We present design and realization of a broadband FMCW Radar working in the Millimeter-Wave (MMW) region. The usable frequency range lies between 91GHz and 102GHz. We use a homodyne radar setup. Thus only one MMW source is necessary which is used for TX and LO generation simultaneously. The complex RX radar signal is calculated by a Hilbert transform in order to avoid a broadband MMW IQ mixer. A...
متن کاملFor Review O nly MIMO Radar Imaging
Through waveform diversity, multiple-input multiple-output (MIMO) radar can provide higher resolution, improved sensitivity, and increased parameter identifiability compared to more traditional phased-array radar schemes. Existing methods for target estimation, however, often fail to provide accurate MIMO angle-range-Doppler images when there are only a few data snapshots available. Sparse sign...
