In this paper recent technical advances for future radar are outlined. Technological challenges such as ultra-broadband radar and multifunctional RF applications along with its operational benefits are discussed. New trends such as the path towards future fully digital frontends as well as distributed aperture radar systems including MIMO and Passive Radar are addressed. In addition the need for efficient and optimized resource management to cope with all the radar sensor flexibilities is addressed as well as advantages in emerging technologies on knowledge based and cognitive radar are pointed out.
