Passive radar systems are used to detect targets in various applications by analyzing the acquired reflected signals. This paper presents a design of passive radar that can operate with signals transmitted from various commercial broadcast and communication systems. Vivaldi antenna structure is designed using CST Microwave studio environment to provide wideband characteristics. A phased array of this antenna is developed to allow digital beamforming to differentiate between direct source and target reflected signals. Signal processing scheme is investigated using Simulink environment to correlated source and target signals. Target range and velocity are estimated based on delay and Doppler shift in the received signal. Analysis revealed that more than one target can be identified using the developed system.
