This paper presents a multi-component frequency modulation (FM) signal model for short-range radar based on the multi-points scattering model of a target, and proves that the method of computing the instantaneous frequency of single frequency is not suitable to the multi-component signal. The method of TLS-ESPRIT combining the mathematical statistics is presented for obtaining the multi-component signal instantaneous frequency (IF). The computer simulation has shown that the method has the high accuracy for measuring the distance.

This paper simply discusses the outer channels and their characteristics of information communication between the fuze and outer environments based on the view that the fuze is an information system, and deeply analyzes the information features of high frequency signal processing that mainly recovers the echo signals and controls the noises instead of picking up the required target information. But it can reduce the uncertainty of the signal caused by noise. The information processing of fuze is mainly completed by the low frequency information processing system.

A novel approach for near-lossless compression of Color Filtering Array (CFA) data in wireless endoscopy capsule is proposed in this paper. The compression method is based on pre-processing and vector quantization. First, the CFA raw data are low pass filtered and rearranged during pre-processing. Then, pairs of pixels are vector quantized into macros of 9 bits by applying block par-tition and index mapping in succession. These macros are entropy compressed by Joint Photographic Experts Group-Lossless Standard (JPEG-LS) finally. The complex step of codeword searching in Vector Quantization (VQ) is avoided by a predefined partition rule, which is suitable for hardware imple-mentation. By control of the pre-processor and VQ scheme, either high quality compression under un- filtered case or high ratio compression under filtered case can be realized, with the average Peak Sig-nal-to-Noise Ratio (PSNR) more than 43dB and 37dB respectively. Compared with the state-of-the-art method and the previously proposed method, our compression approach outperforms in compression performance as well as in flexibility.

针对单轴旋转捷联惯导系统中,传统静基座对准的极限精度受器件误差制约的问题,在对静基座初始对准进行误差分析的基础上,提出了一种利用单轴转台实现的初始对准误差修正技术。利用单轴旋转捷联惯导系统本身具有的转动控制机构,通过转位操作,根据对准稳态误差在不同位置的投影关系计算出误差大小,并对系统加以补偿,从而提高系统对准精度。通过仿真试验可以看出:与两位置对准方法相比,该初始对准误差修正技术能够提高精度,并减少对准时间,同时,可以使水平失准角和方位失准角的对准误差显著下降。
