چکیده
This letter addresses the coherent integration problem for detecting high-speed target. A fast method based on short-time Fourier transform (STFT) and sequence reversing (SRT), that is, STFT-SRT, is proposed. In this method, STFT first employed to obtain velocity improve SNR without additional calculation. After that, SRT presented remove range migration (RM). Finally, (FT) conducted achieve integration. The proposed algorithm can be easily implemented by using complex multiplications FT (FFT). Both simulated real data results demonstrate effectiveness of algorithm.

K-Complex Detection Based on Synchrosqueezing Transform
K-complex is an underlying pattern in the sleep EEG. Due to the role of sleep studies inneurophysiologic and cognitive disorders diagnosis, reliable methods for analysis and detection of this patternare of great importance. In our previous work, Synchrosqueezing Transform (SST) was proposed for analysisof this pattern. SST is an EMD-like tool, which benefits from wavelet transform and reallocat...
متن کاملHuman Activity Recognition Based on Transform and Fourier Mellin Transform
Human activity recognition is attracting a lot of attention in the computer vision domain. In this paper we present a novel human activity recognition method based on transform and Fourier Mellin Transform (FMT). Firstly, we convert the original image sequence to the Radon domain, get the transform curves by transform. Then we extract the Rotation-Scaling-Translation (RST) invariant features by...
متن کاملWavelet transform based fast approximate Fourier transform
We propose an algorithm that uses the discrete wavelet transform (DWT) as a tool to compute the discrete Fourier transform (DFT). The Cooley-Tukey FFT is shown to be a special case of the proposed algorithm when the wavelets in use are trivial. If no intermediate coe cients are dropped and no approximations are made, the proposed algorithm computes the exact result, and its computational comple...
متن کاملRadar Maneuvering Target Detection Based on Scaling Processing and Radon-fourier Transform
A novel long-time coherent integration method, i.e., scaling processing and Radon-Fourier transform (SPRFT), is proposed to detect the low-observable manuevering target, which can compensate the range and Doppler migrations simultaneously. The target signal can be well accumulated as an obvious peak in the centroid frequency-chirp rate (CFCR) domain by simple FT calculations. It is shown that p...
متن کاملOnline Botnet Detection Based on Incremental Discrete Fourier Transform
Botnet detection has attracted lots of attention since botnet attack is becoming one of the most serious threats on the Internet. But little work has considered the online detection. In this paper, we propose a novel approach that can monitor the botnet activities in an online way. We define the concept of “feature streams” to describe raw network traffic. If some feature streams show high simi...
