| Abstract: |
| The paper aims to calculate and analyze the applicability of rocket multi-mode seeker to complex meteorological environment, and provide the reference for the using in the fight. Firstly, with the calculation formula of aerosol attenuation, the relationship between detection distance and wavelength, humidity and visibility was established to calculate the detection distance of optical imaging system under the condition of haze- fog with MATLAB. Secondly, based on Johnston criterion, the probability of target acquisition and recognition at a certain height of optical detection equipment was calculated, to judge the influence of cloud bottom height on detection equipment under cloud environment. Finally, according to the maximum range model of MMW radar and the characteristics of raindrops, the rainfall attenuation model was established to calculate and analyze the influence of rainfall rate on the detection distance of MMW radar. The variation rule of detection distance with humidity and wavelength under haze condition was obtained. The minimum requirement of the seeker for the height of cloud bottom was determined. The change curve of detection distance of MMW radar to different targets with rainfall rate was drawn. The multi-mode composite seeker of rocket gives the advantages of different detection devices to play. It has good applicability to complex weather environment. |
