Chosen results of flight tests of WATSAR system

The paper describes a Synthetic Aperture Radar system currently developed by the Military University of Technology and a Polish private company WB Electronics S.A. in a frame of a project under acronym WATSAR. The project is aimed at designing, development and testing of a terrain imaging radar system operating from a miniature UAV. The paper presents structure and way of operation of the system and its current state of development. The main focus of the paper is directed onto presentation of radar images obtained during two flight campaigns realized in May and July 2015. The paper addresses also the algorithms used for SAR processing and the adopted methodology of in-flight experiments.
