High resolution radar system usually has a massive amount of raw data, so we have to carry out data fusion as quickly as possible. In this paper, we propose a fast clustering algorithm based on single dimensional distance calculation. The proposed algorithm divides raw data into subsets by single dimensional distance, and then merges subsets according to single dimensional distance and set-density...
The linear stepped chirp radar suffers from (a) signal-to-noise ratio (SNR) losses due to amplitude weighting used to suppress nominal range sidelobes both in sub-pulse and inter-pulse compression and (b) range ambiguities due to periodicities in the inverse discrete Fourier transform (IDFT). The paper analyses the root cause of range sidelobes and proposes a new easily realizable non-linear stepped...
This paper introduces a novel method based on decorrelation processing to solve the energy-spillover problem in conventional chirp-pulse stepped-frequency radar processing in order to achieve high range resolution. Compared with previously proposed methods, this method is much simpler to be realized in engineering. Its principle is analyzed in this paper, and its performance is confirmed by simulation...
