To enhance and i mprove the space target detection performance of laser photoelectric detection system in sea level, this paper established the space target characteristics calculation models and signal to noise ratio ( SNR ) model according to the laser detection principle on sea surface and deduced their calculation function and gave appropriate calculation analysis; research ed space target radiation characteristics and derived the total photosensitive surface luminance function in photoelectric detector analyzed the effect factors on SNR in different background luminance. Spectral filtering method was applied to weaken strong luminance influence, and detection distance calculation function was set up based on SNR and the contrast. Through the calculation and experiment analysis, the results showed the calculation models of photoelectric detection performance and SNR were correct and scientific, and the suitable spectral filtering technique could effectively improve SNR..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
