Statistics and analysis of residual FM parameters correlation of male and female voices in English and Chinese, an algorithm for the dimensionality reduction of residual FM parameters based on two-dimensional DCT transform is presented. Remarkable reduction of the correlation of residual fm parameters is obtained. In multi-frame joint coding, DCT dimensionality reduction algorithm achieves coded bits...
Frequency Modulated Continuous Wave (FMCW) Ladar features in high range resolution, small range ambiguity and is capable of acquiring high resolution 3D image. When detecting a moving target, , FMCW Ladar could achieve the target's range and speed information by using Range-Doppler decoupling method, and image the target field in 4D style. This paper describes the principle of FMCW Ladar, analyzes...
This paper presents a multi-target distinguishing method for Frequency modulated Continues Wave (FMCW) Ladar, which is based on velocity compensated rang-doppler decoupling method. The multi-target distinguishing method could be used to detect targets within same range and different speed, and could also be used to detect high speed targets. Simulation results prove the validity of this method, and...
