FIELD: radio engineering, communication.
SUBSTANCE: sea surface simulator for statistical investigation of propagation of sea flicker during operation of laser Doppler radar on low-altitude missiles comprises a continuous wave CO2 laser with a transmitting telescope, a receiving lens coaxially placed in a transmitting channel, with a photodetector array placed in the focal plane of the receiving lens, as well as a multichannel information processing unit, each channel of which includes a channel amplifier, amplitude detector, threshold and control device, connected in series to cells of the photodetector array. The simulator is placed in a closed room near a water basin with a device for simulating waves on the water surface and is directed towards a platform for viewing flicker re-reflections of laser radiation which illuminates a dummy missile suspended over the water basin. The device used for simulating waves is a group of vibrators connected to control signal sources. Channels of the information processing unit include channel storage devices connected to outputs of threshold devices, said storage devices storing the duration of received signals and the time instants of the beginning of the recorded time intervals over which the signals exist, and the outputs of the storage devices act on the interface of the recording device, having a high-speed device for serial polling of code data of channel storage devices, and connected with a timer; the output of the timer is connected to additional inputs of storage devices, which include a device for measuring the time interval of the action of the signal and a coding device.
EFFECT: enabling investigation of radar operation regardless of weather conditions.
