Abstract—The imaging quality of tomography SAR is limited by the low number of flight tracks and their non-uniform distribution. In this paper, a new 3-D imaging algorithm is proposed for tomography SAR based on the improved interpolated array transform. The key point of the proposed algorithm is the introduction of the projection technique into the(More)
OBJECTIVE To investigate the clinical value of combined determination of in vitro allergens and fractional exhaled nitric oxide (FeNO) in indentifying children at a high risk of asthma among those with recurrent wheezing. METHODS A total of 148 children with recurrent wheezing (0.5-6 years old) were enrolled as study subjects, and 80 healthy children who(More)
Time-frequency analysis method to locate the thin layer in GPR detection is proposed in this paper. It is used to improve the recognition ability of GPR. Several time-frequency analysis methods as Short Time Fourier Transform (STFT), Wavelet Transform (WT), S Transform, General S Transform and Wigner Transform are compared in this paper. Simulation and(More)
