Abstract

A high-speed and high-resolution block adaptive quantizer is designed and implemented for current synthetic aperture radar imaging systems. To solve the problem of exponential growth in complexity due to the requirements of large BAQ output wordlengths, input scaling and hybrid comparison architectures are proposed. Significant saving in the threshold memory size is achieved and a good balance of path delay and arithmetic complexity is attained by two techniques. The proposed design supports 291MHz and 12-bit ADC with output wordlengths of 2, 3, 4, 6 bits.
