Improved Bandwidth and Performance for a Digital MTI Signal Processor.

Abstract

The important results are summarized in this report. The basic problem studied was the effect of using various algorithms for specifying the digital filter coefficients for a moving target indicator (MTI) radar signal processor in terms of improving the usable percentage of the pulse repetition frequency (PRF) while retaining an acceptable level of clutter attenuation. This study concentrated on the design of multiband filters for suppression of both ground and weather clutter using a linear-phase filter algorithm. Furthermore, the substitution of minimum-phase filters for the aforementioned design examples plus high-pass filters (HPF) for ground clutter suppression was investigated. Finally, the role of MTI filter in frequency response was studied when the PRF was staggered, either on a pulse-to-pulse or block-to-block basis. (Author)
