ABSTRACT

This chapter explores the application of high performance embedded computing to radar systems, beginning with a high-level description of some basic radar principles of operation and fundamental signal processing techniques. RAdio Detection And Ranging a technique for detecting objects via scattering of radio frequency electromagnetic energy, traces its history to the early days of World War II when systems such as the British Chain Home were employed successfully for the detection of aircraft. Some actual radar signal processors developed at MITLincoln Laboratory are presented as examples of what can be accomplished in this domain and how capability has evolved with time. Increasingly, radar systems have incorporated multichannel antenna designs in order to deal effectively with jamming and the problem of clutter suppression from a moving platform. The chapter considers the case of stationary radar and moving target, where the clutter has zero Doppler and the target has nonzero Doppler, permitting effective separation of target from clutter.
