This method reduces the computational complexity of the ML method. By using numerical simulations, the performance of the new approach is verified. Also we apply the algorithm to the raw data of an X-band airborne SAR with 3 m /spl times/ 3 m resolution. Moving targets are successfully focused.","PeriodicalId":216583,"journal":{"name":"Proceedings of the 2003 IEEE Radar Conference (Cat.

We study the methods that convert multi-channel radar data into dual along-track monopulse SAR signals of the radiated scene. A 2D adaptive filtering method, that projects the data in one synthesized SAR channel into the signal subspace of the other, is used for blind calibration of the monopulse SAR signals and generation of the MTI statistic. The merits of these algorithms are studied using the data from the multi-channel airborne radar measurement (MCARM) system that has been developed by the Air Force Research Laboratory at Rome, New York.","PeriodicalId":216583,"journal":{"name":"Proceedings of the 2003 IEEE Radar Conference (Cat.

The radar operates in real-time with 3Hz update rate. In order to detect the motion of people moving with different velocities, a digital moving target detection (MTD) filter has been developed which is implemented in the software of the radar. The MTD filter is an IIR high-pass filter and it helps reject the stationary (time history invariant) clutter. Results on the time vs. slow-frequency (Fourier transform of slow-time response) distribution for targets moving at different velocities are presented for a given update rate. The transfer function of the MTD filter as a function of a target velocity is also presented for a given update rate.","PeriodicalId":216583,"journal":{"name":"Proceedings of the 2003 IEEE Radar Conference (Cat.

The novel microstrip antenna array, designed, fabricated, in numbers and tested, has offered a fairly wide bandwidth (4%) in X-band, a high gain (>30 dB) with a good return loss (< -15 dB) and low sidelobe (> -25 dB) pattern performance through the bandwidth, and weighs only 1.2 kg with its back-up structure.","PeriodicalId":216583,"journal":{"name":"Proceedings of the 2003 IEEE Radar Conference (Cat.

The dish is constructed using lightweight, thin film technologies used in spaced-based platforms. Seaming two parabolic dish films together forms a lenticular. One film is coated with a silver flake conductive paint, and the other is RF transparent. The lenticular is inflated to hold the parabolic shape of the dish. The lenticular is attached to the inside of an inflatable spherical radome. The radome provides environmental protection to the thin film lenticular. The lenticular and radome are designed such that the focal point is located on the surface of the radome. An RF feed is attached to the radome at the focal point. The gain of the dish is measured using the sun as an RF source. Solar gain measurement data is presented showing the measured peak gain from the sun and the width of the main beam.","PeriodicalId":216583,"journal":{"name":"Proceedings of the 2003 IEEE Radar Conference (Cat.
