In recent years, radar, especially frequency-modulated continuous wave (FMCW) has been extensively used in non-contact vital signs (NCVS) research. However, current research does not work when multiple human targets are close to each other, adjacent lie the same resolution cell. this paper, a novel method based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN)–inde...

Radar collision prediction systems can play a crucial role in safety critical applications, such as autonomous vehicles and smart helmets for contact sports, by predicting impending just before it will occur. Collision algorithms use the velocity range measurements provided radar to calculate time collision. However, used contain significant clutter, noise, inaccuracies which hamper reliability...

This paper investigates the feasibility of extracting characteristics sealed boxes based on range profiles using a millimeter-wave automotive FMCW radar. Radar is one key basic sensors for driving assistance and collision avoidance. Target classification radar has been studied extensively, yet detection material requires further investigation to improve situational awareness better judgment. We...

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...
