Micro-Doppler based target recognition and classification methods are new approach of great significance. Translation will induce translation, slope and fold of micro-Doppler which will make it difficult to extract micro-Doppler, i.e., number of parameters in Hough method will be added. To solve the problem, we derived the motion, signal as well as Doppler(More)
The wavelet transforms domain LMS algorithm is integrated with variable step-size LMS algorithm and BLMS algorithm, from which a new wavelet transforms domain variable step-size BLMS adaptive algorithm is presented. The algorithm has advantages of the above three algorithms, it can reduce the cross-correlation of input signals effectively and can overcome(More)
Compressive sensing (CS) has been introduced into inverse synthetic aperture radar (ISAR) imaging with partial measurements. However, in the case of transmitting sparse frequency-stepped chirp signal (FSCS), the CS-based method will produce an irregular range cell migration (IRCM) problem in the recovered high-resolution range profiles (HRRPs). The IRCM is(More)
A novel method for three-dimensional (3D) image scaling of spinning target is proposed via wideband and narrowband radar images registration. It gets the scaling factor by extracting the difference of two images, which are obtained via two distributed radar in space. The size and angle of a distorted 3D image obtained via wideband radar, is interrelated(More)
A novel method for three-dimensional (3D) imaging by combining a narrowband bistatic multiple-input-multiple-output (MIMO) radar with two uniform linear arrays and inverse synthetic aperture technique is presented. During a short coherent processing interval (CPI), the motion of the target can be equivalent to a synthetic uniform linear array, which,(More)
A new variable-step-size LMS algorithm is proposed, and it performance is analyzed. Simulation results indicate that the performance is superior to that of existing VSS algorithm and NLMS algorithm. The proposed algorithm is then applied to adaptive noise jamming cancellation system; the computer simulation shows superior performance over the NLMS algorithm(More)
