Fashionable FMCG clothing brands have emerged in large numbers, and fast fashionable and personalized clothing is increasingly favored by young people. In this era of rapid renewal, clothing has obviously become a fast moving consumer good. China’s textile industry continues to develop, and the speed of development accelerates, coupled with the introduction and promotion of the use of Western textile technology, making the pattern design of Chinese textiles develop more quickly. The long-term disconnection between product pattern design and product production has led to the fact that the research on product pattern has been only on the plane, so there is an urgent need to improve the design level of product pattern and the market competitiveness of products through systematic research on product pattern. Newton’s iteration is an important research content of nonlinear theory, which is a hot spot in the field of scientific research at present. Newton’s iteration is a common method for finding the roots of nonlinear equations, which has at least second-order convergence speed, but requires the calculation of first-order derivative values. In this paper, a preliminary discussion on the design method of pattern design based on Newton’s iterative algorithm is conducted to explore a new way of personalized pattern design while using nonlinear graphs as pattern design materials. The experimental results show that the average value of EME of Newton’s iteration algorithm is 3.479 and 2.072 higher than that of AVG Filter and CB Filter, respectively, and the difference of pattern generation accuracy between CB Filter and AVG Filter is not much, so the accuracy of Newton’s iteration algorithm for pattern generation is better than that of CB Filter and AVG Filter. Therefore, it is proved that it is feasible to transform the special texture effect based on Newton’s iteration algorithm into fabric.

In multiple input multiple output (MIMO) radar systems, the design and development of orthogonal frequency division multiplexing (OFDM)linear frequency modulation (LFM) waveforms is one the most challenging and crucial tasks. Similar to this, increasing the pulse properties of spatially synthesised signals is also crucial in MIMO systems since it makes it possible to successfully eliminate grating sidelobes. Various joint optimization strategies are established in the various existing research works to enhance the overall performance of radar communication systems. Even yet, it has drawbacks including harder to understand computations, false detection rates, and reduced efficacy. Therefore, the proposed work intends to develop an integrated particle swarm optimization (PSO)sequential quadratic programming (SQP) mechanism for improving the pulse compression properties and suppressing the grating sidelobes. Here, a modification is made to the designed LFM waveform to improve its frequency steps while maintaining balanced sidelobe and orthogonal features. By using the different pulse compression properties, the performance and outcomes of the proposed PSO-SQP based joint optimization model are evaluated and compared through simulation analysis. In this assessment, the average pulse compression, cross correlations, transmit beam patterns, and correlation properties are evaluated for varying spatial synthesis signals for the existing methods with the proposed method. Moreover, the estimated values of these parameters are compared with the conventional and proposed PSO and joint optimization techniques. The proposed method produced better results as compared with the existing methods with respect to various pulse compression properties such as auto-correlation side lobe peaks (ASP) and cross-correlation side lob peaks (CP). Based on the results, it is found that the proposed mechanism is capable of achieving the best ASP (19.4 dB), CP (14.02 dB) and ASLE (0.3745) among all, so assures the high range of resolution of the radar communication system.

In this paper we study the code design problem of a new form of linear frequency modulation phase-coded (LFM-PC) hybrid signal with wide Doppler tolerance based on a range-Doppler discrete ambiguity function (DAF) to get better detection performance and anti-jamming capability. The DAF of the LFM-PC inter pulse signal is derived within the Doppler tolerance. Two optimization models are established. One is single pulse sequence design (SSD) for Doppler tolerance extension based on minimum integral normalized sidelobe level (INSL); the other is multi pulse sequence set design (MSSD) for signal orthogonality based on the minimizing sum of the normalized DAF sidelobe (NDAFSL) and discrete cross ambiguity function (DCAF). Two low-complexity signal optimization methods based on alternating direction method of multiplier (ADMM) are proposed, respectively. The simulation results show that the optimized signals have either wide Doppler tolerance or good orthogonal performance, and the optimization methods (i.e., SSD-ADMM and MSSD-ADMM) have the characteristics of fast convergence speed and low operation amount.
