The satisfactory laser echo rate under stochastic passage characteristics indices

Based on a CCD-imaging tracking system with a laser range-finder,the laser echo rate and the distribution of laser missing detection is studied.Under the direction of satisfactory theory,a satisfactory predictive gain design method with prescribed performance specifications of estimation error variance,regional polar and stochastic passage characteristics,is proposed by solving bilinear matrix inequalities.The proposed filter can guarantee the echo rate of the laser range-finder being large,and distribution of missing detection period being uniform,so that the flight path detected by the tracking system is to be stationary and continuous to the expected extent.Numerical example indicates a satisfactory performance of the proposed gain.
