6.MATLAB仿真 参考文献: 序言 最近正在学习基于毫米波雷达的SAR成像。接触的第一个算法就是时域的BPA算法,网上虽然也有不少文章,但是我认为写的或多或少都不是很完善。经过大致的学习后,我按照自己的理解整理出相关思路,以供大家共同学习讨论。 1.毫米波雷达发射信号与回波信号基本推导 首先自然是毫米波雷达基本...
This algorithm distinguished the effective reflection data from the background data by determining the distance threshold between the data points. The 3D imaging of the defect was then performed in MATLAB. The proposed method was validated using both gprMax simulations and laboratory test models. The...
The SARbackprojection MATLAB code is an implementation of the BackProjection algorithm. The code takes the raw data in the form of complex-valued signals and uses Fourier transforms to convert it into time-domain data. The data is then processed using mathematical calculations to create the final...

L1loss function is minimized by Adam [20] algorithm. The overall process of PBPN is shown in Algorithm 1. Algorithm 1.. Progressive Back-Projection Network for COVID-CT super-resolution. Require: Learning ratel, batch sizem, and iteration epochE Input: The training set{ILRi,IHRi}i=1N ...
Level-2 MATLAB® S-functions must implement the following callback methods: setup –Specifies the sizes of various parameters in the SimStruct, such as the number of output ports for the block. Outputs –Calculates the output of the block. Terminate –Performs any actions required at the termi...
In this journal, Cheng has proposed a backpropagation (BP) procedure called BPFCC for deep fully connected cascaded (FCC) neural network learning in comparison with a neuron-by-neuron (NBN) algorithm of Wilamowski and Yu. Both BPFCC and NBN are designed to implement the Levenberg-Marquardt me...
Our cell detection algorithm steps (implemented using the image processing toolbox in MATLAB, R2017; function names in italic) were as follows: (1) background subtraction using morphological top-hat filter imtophat (structural element: “disk,” size: 4); (2) binarization by imbinarize using a...
classification of each algorithm to decompose a2304x51matrix or48x48x51tensor data. Both matrix and tensor data were built fromdataset/demo.avifile. The experiments were performed in a Intel Core i7-3740QM CPU 2.70GHz with 16Gb of RAM running MATLAB R2013b and Windows 7 Professional SP1 64 ...
In addition, they proposed a recursive constraint projection (RCP) algorithm for data segmentation, which also proves effective for processing streaming data. Hassan et al.30 presented the concept of Haptic Authoring, which involves the creation of novel virtual textures through the interpolation of ...
