摘要： A detection method for preventing an automobile from colliding is applied to an automobile. The detection method includes the following steps: step (a): providing at least two detection devices, each detection device is used to measure a predetermined information of the automobile. A one-stage linear Kalman filter in each device is used to enhance the signal-to-noise ratio of the predetermined information. In step (b): utilizing the one-stage linear filter to receive the predetermined information and obtain a corrected information from the predetermined information after the signal-to-noise ratio is enhanced. In step (c): calculating the corrected information to obtain a component information having vector components of a first direction and a second direction. In step (d): enhancing the signal-to-noise ratio to enable the component information to be a contrast information. Accordingly, the convergence time of calculating the contrast information can be substantially reduced. The position variation of the surrounding moving objects can be accurately estimated to prevent the sudden collision in a short time.

摘要： A method and system is proposed for use by a moving station (such as a jetfighter) for radar tracking of a moving target (such as an air-to-air missile). The proposed method and system involves the use of a hybrid FSK/LFM (Frequency Shift Keying & Linear Frequency Modulation) scheme for acquiring a collection of raw radar data, a first Gaussian-noise filter array of one-stage linear Kalman filters for S/N-enhancement of the raw radar data, a trilateration module, and a second Gaussian-noise filter array of one-stage linear Kalman filters for S/N-enhancement of the trilateration-resulted radar data. These features allow the radar tracking of moving objects to be more fast and accurate.
