Spotlight-mode synthetic aperture radar (spotlight-mode SAR) synthesizes high-resolution terrain maps using data gathered from multiple observation angles. This paper shows that spotlight-mode SAR…
Convolution backprojection image reconstruction for spotlight mode synthetic aperture radar
Convolution backprojection (CBP) image reconstruction has been proposed as a means of producing high-resolution synthetic-aperture radar (SAR) images by processing data directly in the polar…
The use of residue number systems in the design of finite impulse response digital filters
A technique is presented for implementing a finite impulse response (FIR) digital filter in a residue number system (RNS) and a new hardware implementation of the Chinese Remainder Theorem is proposed for an efficient translation of residue coded outputs into natural numbers.

A mathematical analysis of the error correction algorithm is presented which suggests a new design with considerably reduced hardware complexity, a hardward architecture for a high speed pipelined error checker is proposed.
Self-checking properties of residue number error checkers based on mixed radix conversion
The potentially useful properties of this self-checking error checker, modified by means of mixed-radix conversion, are examined.

This paper outlines PSO and provides a comparison to the GA for IIR filter structures and shows that both techniques are capable of converging on the global solution for multimodal optimization problems.

Structured stochastic optimization algorithms that are effective on multimodal error surfaces are introduced, with particular attention to the particle swarm optimization (PSO) technique.
The use of orthogonal transforms for improving performance of adaptive filters
It is shown that the effect of an ideal transform is to convert equal error contours that are initially hyperellipses in the parameter space into hyperspheres, and simulations suggest that transforms can be found which give much improved performance in a given situation.
A new adaptive IIR filter
A family of stochastic approximation variants of the Steiglitz-McBride identification scheme - is developed for adaptive IIR filtering. Parameter convergence is shown by computer simulation. An…
