Summary:
WiMAX, the Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides wireless data in a variety of ways, from point-to-point links to full mobile cellular type access. Passive radar systems utilize broadcast, communications or radio-navigation transmissions as their illuminating signal in bistatic (or multistatic) radar geometry. Over the past decade or more, there have been increasing interests in the employment of illuminators of opportunity for passive radar, such as FM radio, television, digital radio and television, cellphone downlink, and satellite broadcast or radionavigation signals [1]-[4]. Such signals, however, are not optimized for radar applications, therefore it is necessary to analyze their behaviors in order to understand their performance, to choose which signals to use, and how best to process them. This paper presents the ambiguity function of WiMAX signals and an analysis on the suitability of WiMAX signal for passive radar applications. Simulation results as well as experimental results based on a MIMO-OFDM (Multiple Input and Multiple Output - Orthogonal Frequency Division Multiplexing) testbed are presented.
