Abstract

FIELD: measurement equipment.

SUBSTANCE: device includes an instrument compartment that comprises the equipment determining the received signal radio-technical characteristics, which is directly connected to a radioaltimeter determining the altitude of availability or absence of a radar signal at different altitudes, air temperature, humidity and pressure sensors. Besides, the instrument compartment includes a power supply unit, a radio transmitting equipment implementing the transfer of the received data to the consumer. Depending on the required recording speed of availability and absence of a radar signal at different altitudes, the stabilising device can perform simultaneous functions of a braking device at different altitudes.

Description

The essence of the invention

The invention relates to information-measuring equipment and can be used in radio control systems to determine the presence or absence of a radar signal at different heights above the water surface and with the subsequent transfer of the received data to a consumer located outside the radar horizon of the studied radar in real time.

Description of the invention

A device for determining the presence or absence of a radar signal at different heights above the water surface. The device relates to information-measuring equipment and can be used in radio control systems to determine the presence or absence of a radar signal at different heights above the water surface, taking into account air temperature, pressure and humidity, followed by transmitting the received data to a consumer located outside the radar horizon of the studied radar in real time.

The object of the invention is a device launched from a ship, aircraft or shore by a missile projectile (in particular, an anti-aircraft guided missile or air-to-air missile) or free fall after being dropped from an aircraft, determining the height of the presence and absence of a radar signal at different heights above water surface, taking into account air temperature, pressure and humidity, followed by the transmission of the data to a consumer located outside the radar horizon aemyh radar in real time.

Known rotating ammunition for US patent No. 4050381, CL. 102-4, from 12.04.72, this design is a self-aiming combat element, which includes the warhead, instrument compartment and parachute system. A common sign with the design of the combat element proposed by the authors is the presence in the composition of the analog of a device stabilizing the flight of the vehicle (in relation to the analog, this is a parachute).

Unlike the analogue in the proposed design, the device is not intended to defeat military equipment, but to determine the presence or absence of a radar signal at different heights above the water surface. Design features are the lack of homing equipment and the presence of equipment in the instrument compartment, which determines the radio characteristics of the received signal, directly related to the radio altimeter, which determines the height of the presence or absence of the radar signal at different heights, as well as the presence of air temperature, humidity and pressure sensors at the measurement point. The instrument compartment also has radio transmitting equipment transmitting the received data to the consumer.

This allows us to conclude that there is a causal relationship between the totality of the essential features of the claimed technical solution and the achieved technical result.

The objective of the invention is to create an element that determines the presence or absence of a radar signal at different heights above the water surface and the transmission of these data to a consumer who is outside the radar horizon of the studied radar.

The specified technical result is achieved by the fact that in the device containing the instrument compartment and the device stabilizing the flight of the device vertically down, the instrument compartment is equipped with equipment that determines the radio characteristics of the radar signal, temperature, pressure, humidity, power supply, altimeter and equipment transmitting the received data to the consumer.

The described device operates as follows. At a given point in the flight path of the rocket projectile (PC), the head part — the apparatus — is separated from the jet engine or any other carrier at a given height. After separation at the initial time, the device, due to initial disturbances during separation, performs an unstabilized flight. Then, a device that stabilizes the flight path of the device is triggered, depending on the necessary speed of detecting the presence or absence of a radar signal, it can be a parachute that simultaneously performs the function of a braking device, or a stabilizer made of solid material with the necessary strength parameters. The instrument compartment fixes the moment of stabilization of its planning with the moment it begins to decline vertically downward, while the unit that synchronizes the radio characteristics of the signals from the radar, altimeter, pressure, temperature and humidity sensors is launched simultaneously with the data on the radio characteristics of the signals from the radar, altimeter, sensors pressure, temperature and humidity in real time using a transmitter are transmitted to the consumer.
