The method for measuring the strain of an object using an optical fiber and a frequency modulation(FM) coupled cavity semiconductor laser is proposed.This method uses the coherent FM heterodyne principle of the Michelson interferometer and can avoid the π/2 nonreciprocal phase bias and phase shifting problem existing in general fiber optic interferential sensors, the maximum detection range is limited by the coherent length of the semiconductor laser and its relative factor.

Some angle association algorithms have been developed so far but how to extract the available observations used for association from all angle observations has been less discussed. This paper presents a preprocessing algorithm of angle association which is deduced with maximum detection range of each sensor and relative location of sensors, and gives several new concepts such as association flare angle, candidate observation set and available observation set. Using this preprocessing algorithm, the number of association observations and false targets will be decreased sharply, and the probability of successful association and the real-time performance of the system will be improved.

This paper investigates the approach to estimate the maximum detection range of an infrared point_target against sky background based on the minimum resolved contrast(MRC)criteria. Firstly, the characteristics of radiation propagation and attenuation in the atmosphere, and the power response of a contrast_limited optoelectic system are analyzed, the apparent contrast model of a target is developed, and the detection range equation dependent on the aerosol extinction coefficient and range parameter are derived. Secondly, other parameters such as temperature difference and emissivity of target and sky, molecular absorptive transmittance, instantaneous field of view (IFOV), contrast threshold and radiant wavelength are discussed in detail. Finally,the numerical simulations related to infrared point_target detection range are executed using typical atmospheric data output form LOWTRAN7 code.
