METHOD FOR HOMING MISSILES to ground target at alternating target-background contrast and TARGETS COORDINATOR FOR ITS IMPLEMENTATION

摘要

The group of inventions relates to systems of missile homing to ground targets and can be used for the class of "ground-ground" missiles. The homing method for a missile on a ground target with alternating target-background contrast at which to form the flight control signals of missiles in the target coordinator a radar in the millimeter wavelength range is used, and the thermal in infrared in wavelength range of mutual contrast of the targets and surface background. The radar and thermal mutual contrast targets and ground background are analyzed mutually in space and mutually synchronized in time by separate focus echoes of targets with single-pulse emitter of millimeter waves and thermal radiation of target in infrared receiver due to selection in the two polarization selectors. The flight control signals of missiles are formed from the original signal of millimeter range receiver in the presence of a radar contrast target or output of an infrared signal receiver in the presence of thermal contrast targets against the background of the surrounding locality. Coordinator of the targets for the homing missiles at surface target with alternating target-background contrast consists of a parabolic mirror, in the geometric center of which there is placed a monopulse transmitter which is connected to a series connected transceiver of millimeter wavelength range and block for formation of the flight control signal of rockets, receiver of infrared range located in focus of parabolic mirror and connected to the second input of the block forming the rocket flight control signals. Between monopulse transmitter and infrared receiver first and second polarization selectors are placed. Between the output of infrared receiver and the second input of the formation of the missile flight control signal control switch is included, the control input of this one is connected to the output of transmitter-receiver of millimeter range. The group of inventions eliminates the effect of the energy contrast of targets sign on the surrounding background areas.
