Rescue Radar System with Array Antennas
Transactions of the Society of Instrument and Control Engineers, 2008 The purpose of this study is to improve rescue radar system with array antennas so that it can quickly identify far-off survivors under rubble. Authors focused on time-variable elements from the respiration of a survivor awaiting rescue in order to remove clutter components, such as the rubble.

Miniaturisation of high-frequency SURFACE wave radar transmitting antenna
The Journal of Engineering, 2019 Antennas operating in the high-frequency (HF) bands are generally relatively large in size, which severely limits the application of the antennas. Therefore, miniaturisation of the antenna is necessary.
