The integration of wireless communication and radar sensing is now getting a huge interest from researchers of two big societies, wireless communication and radar. The road map to the final goal and individual solutions to the challenges might differ in developing the Integrated Communication and Sensing (ICAS) system. However, the electromagnetic signature of the targets will be still valid for all variants of the ICAS system because the detection, localization and classification of the targets are involved. Therefore, this paper presents a study on static reflectivity and micro-Doppler signatures of drones together. To acquire the required data, the state-of-the-art measurement system, BiRa, is used.
