Paper Abstract

Conventional phased array radar is to delay the signal between arrays by means of controlling signal phase indirectly in order to realize broadband and wide-angle scanning. This method makes system more complex. This paper presents frequency-domain phase weighting method to achieve accurate delay for wideband digital signal, elaborates algorithm principle of the method .At the same time, FPGA implementation is proposed and the factors of affecting delay precision are analyzed. Experimental results show that this method can achieve high-accuracy time delay for wideband digital signal, making FPGA implementation easily and reducing the inherent delay of signal processing, thereby reducing the hardware resource consumption.
