In this paper, we proposed a new packet detection algorithm with high performance and low hardware complexity for chirp-spread-spectrum (CSS) in AWGN channel. There are two typical conventional packet detection algorithms. First, the conventional algorithm based on mixed-correlation (CABMC) has a good performance by using matched filter to remove unused band noise, but the algorithm has a high hardware...
Coherent Scatterers (CSs) are usually detected in SAR data using spectral correlation techniques, by evaluating multilook images in the range direction. The first part of the paper demonstrates an alternative way to detect CSs by exploiting their inherent strong phase stability along frequency. The main advantage of the technique is the absence of a spatial average (necessary in the original procedure),...
