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 کاملRadar ATR of Maritime Targets
A short overview of ship ATR schemes in general is followed by an in-depth analysis of the use of HRR profiles under shallow depression angles that suffer from the influence of multipath and atmospheric duct phenomena. The critical issue of defining appropriate training and testing profiles or feature vectors derived therefrom is addressed. Some ideas how to mitigate the influence of multipath ...
متن کاملPhase Error Correction for Approximated Observation-Based Compressed Sensing Radar Imaging
Defocus of the reconstructed image of synthetic aperture radar (SAR) occurs in the presence of the phase error. In this work, a phase error correction method is proposed for compressed sensing (CS) radar imaging based on approximated observation. The proposed method has better image focusing ability with much less memory cost, compared to the conventional approaches, due to the inherent low mem...
متن کاملRadar Imaging for Combatting Terrorism
Radar, and in particular imaging radar, have many and varied applications to counterterrorism. Radar is a day/night all-weather sensor, and imaging radars carried by aircraft or satellites are routinely able to achieve high-resolution images of target scenes, and to detect and classify stationary and moving targets at operational ranges. Short-range radar techniques may be used to identify smal...
متن کاملEvaluating the Radar Cross Section of Maritime Radar Reflectors Using Computational Electromagnetics
− This paper presents results from calculating the radar cross section (RCS) of two maritime radar reflectors using the method of moments. The Echomaster 152, although smaller in size, produces a higher maximum RCS than the Echomax 230 that includes three layers of corner reflectors. The Echomaster 152 also has deeper nulls in the RCS pattern, which means it is less detectable at those angles.
