It is essential to have fine range and cross -range resolution to characterize objects near and under severe clutter. T his Tutorial is divided into five parts.\n• The Early History of Battlef ield Surveillance Radar: Battlefield surveillance from manned and unmanned aircraft\, along with early experiments in fixed and moving target detect ion and foliage penetration are covered. There were some very interesting developments in radar technology that enabled our ability to detect fixed and moving objects in dense clutter. Examples of airborne phased array ant ennas and UWB radars will be summarized.\n• Surveillance Radar Modes: A summary of radar modes along with models of distributed clutter are shown. Analysis for Displaced Phase Center Array\, Doppler Beam Sharpening\, Gro und Moving Rarget Indication are illustrated from early phased array anten na radars.\n• UWB Phased Array Antenna: Electronically scanned antennas are widely used for surveillance of large areas. Wideband waveforms place a significant demand on the ESA design to maintain gain and sidelobe chara cteristics. Design of ESA systems with time delay steering and digital bea mforming will be described.\n• UWB Synthetic Aperture Radar (SAR): A bri ef description of several UWB surveillance SAR systems will be provided\, along with illustrations of the SAR image and fixed object detection capab ility. Techniques developed for ultra-wideband and ultra-wide-angle image formation will be presented.\n• Ultra Wideband Frequency Allocation Issu es: A summary of world wide regulation on waveform designs is presented. T he processes for obtaining frequency allocation are important in the new r estrictions are summarized. A concept of cognitive radar that selects the waveform for a geographic region and adaptively cancels the radio frequenc y interference is presented.\n• UWB Ground Moving Target Indication: Spa ce time adaptive processing (STAP) has been used for over 20 years for det ecting and tracking moving targets in clutter. As the resolution is improv ed for target characterization\, the limits of STAP are tested. This secti on will discuss two approaches for increasing the bandwidth and maintainin g geolocation accuracy: wideband STAP and Along Track Interferometry.\n• New research in Multi-mode Ultra-Wideband Radar\, with the design of both SAR and moving target indication (MTI) FOPEN systems. The last section of the tutorial will illustrate new technologies that have promise for futur e multimode operation: simultaneous SAR and GMTI in a multichannel radar.\ n\nSpeaker(s): \, Mark Davis\n\nRoom: Audytorium Centralne\, 1st floor\, B ldg: Faculty of Electronics and Information Technology\, Warsaw University of Technology\, ul.
