Proceedings of the 2002 IEEE Radar Conference (IEEE Cat. No.02CH37322) Pub Date : 2002-08-07 DOI: 10.1109/NRC.2002.999746

These arrays are capable of pointing a beam in any direction at any time. This allows the radar to perform both 360/spl deg/ search and high update rate track modes simultaneously. To manage the radar's resources efficiently, shorter coherent processing intervals (CPIs) should be used for nearby or large targets. However, shortening the CPI effects STAP performance by increasing the amount of Doppler space that is lost to the clutter null. This paper analyzes the useable Doppler space performance of short CPI STAP. It is shown that CPIs as short as 6 pulses can be used to track high velocity targets. Short CPI STAP performance is analyzed theoretically and by simulation.","PeriodicalId":448055,"journal":{"name":"Proceedings of the 2002 IEEE Radar Conference (IEEE Cat.

It is intended for surveying building structures and works. The characteristic feature of this device is the possibility of obtaining in a sounding plan the microwave images featuring a high resolution attaining 2...3 cm. The main application of this device includes the survey of building constructions to reveal their internal structure and defects. An arched aperture in a brick wall was studied with help of the radar to search metallic beams. The goal of investigation was evaluation of the load-carrying ability of the wall.","PeriodicalId":448055,"journal":{"name":"Proceedings of the 2002 IEEE Radar Conference (IEEE Cat.

The basic concept is that the phase history measurements include the realistic effects of MB interactions. These measured phase history data are decomposed into contributions due to the desired single-bounce (SB) scattering events and the undesirable MB interactions. An enhanced quality image can be constructed by retaining only the SB contributions.","PeriodicalId":448055,"journal":{"name":"Proceedings of the 2002 IEEE Radar Conference (IEEE Cat.
