The following topics are dealt with: airborne radar; MTI & ECCM; waveform design and synthesis; advanced interferometric SAR technique; active phased array; data fusion & KBS; spaceborne SAR and meteorology.
This talk will try to briefly review what developments have had an impact on radar (that is, what concepts and technology have made radar of value in the past), what radar concepts and technology were important in the past but might not be so important in the future, what things appear to be of current interest in radar but are not as likely to see lasting utility (that is, ideas that one should examine...
The modeling of the clutter echoes is a central issue for the design and performance evaluation of radar systems. The aim of this paper is to describe the state-of-the-art approaches to the modeling and understanding of land and sea clutter echoes and their implications on performance prediction and signal processors design. The tutorial is mainly divided in 5 parts: (i) Radar sea and ground clutter...
This course provides even relative newcomers to radar an appreciation of radarpsilas uses today, and a true understanding of the nature of radar and its subsystems and of the underlying principles of the fascinating advances being made today and so widely reported in our conferences and other technical media. The course is an excellent ldquowarm-uprdquo for RadarCon-08!
Since its inception 30 years ago perhaps no innovation in radar technology has made such a tremendous impact on the field as that of radar interferometry. Radar interferometry uses two or more observations separated in either time or space to measure fraction of a wavelength scale range differences between the two observations. Radar interferometry is used by scientific, commercial and government...
It has been remarked that interest in the subject of bistatic radar has varied cyclically, with a period of about fifteen years. The very first radars were bistatic, until T/R switches were invented. Interest was revived in the 1950s/1960s, with semi-active homing missiles and the SPASUR system, then died away. The second resurgence was in the mid-1970s to mid-1980s, with systems such as SANCTUARY...
Space-time adaptive processing (STAP) is an advanced signal processing methodology for the Ground Moving Target Indication (GMTI) mode of airborne and space borne surveillance radar systems. It is used to mitigate motion-induced spread-Doppler clutter that interferes with the echo from ground targets. The course will develop and clearly illustrate the GMTI problem from first principles, showing the...
Future multi-mission / multi-mode sensors and radio frequency systems will have to operate in electromagnetically dense signal environments. Furthermore, a diverse cadre of concepts may result in a variety of fielded systems, all operating in close proximity to each other. While this ever growing collection of concepts bodes well for the rapid transition of new technology, these systems must share...
Summary form only given.Fundamental tools for radar signal analysis - the matched filter response and the ambiguity function - are briefly discussed and demonstrated on basic signals: LFM pulse, coherent pulse train and a coherent train of LFM pulses. Advanced pulse compression signals and sidelobe reduction techniques are then studied, including: frequency modulation (Costas, NLFM, multi-carrier),...
Space-Time-Adaptive Processing (STAP) is becoming an integral part of modern airborne and space-based radars for performing Airborne Moving Target Indicator (AMTI) and Ground Moving Target Indicator (GMTI) functions. STAP is an application of optimum and adaptive array processing algorithms to the radar problem of target detection in ground clutter and interference with pulse-Doppler waveforms and...
