Description

The utility model relates to radar and can be used in the design of medium-range portable radars (radars) (up to 40 ÷ 50 km) designed to detect low-flying targets against local objects and passive interference.

The development of air attack weapons (tactical and attack aircraft, unmanned aerial vehicles, cruise missiles, guided air-to-surface missiles, guided aerial bombs and cartridges, etc.) capable of operating at low and ultra-low altitudes under the cover of interference causes the need to create specialized radars capable of monitoring airspace at the above heights, being mobile and transportable (at present, the location of the radar is quickly determined I am an adversary), and also have good noise immunity parameters.

Known portable radar "Mongoose", designed for reconnaissance of ground, surface and low-flying targets, which automatically in continuous mode in the millimeter range searches, detects and displays targets (see the Internet site http://www.ust.com.ua / main). The use of a solid-state transmitter made with transistors with a low radiation power (0.01-1.0 W) makes it difficult to detect radar by means of electronic intelligence. However, with a decrease in the wavelength of the working wave, the dependence on weather conditions (rain, thunderstorms, vibrations of tree leaves, etc.) increases.

Also known is the modular design of the portable Doppler pulsed coherent radar "Kredo-1E" with a solid-state multiliter reference oscillator and a flat antenna array (AR), a waveguide-slot type, driven into rotation by an electric drive mounted on a tripod, combined with a rotary high-frequency current collector, on the upper the movable part of which is fixed specified AR. This radar has a remote control panel and an autonomous power source in the form of rechargeable batteries and operates in the centimeter wavelength range (see the “Arms of Russia” catalog. M., “Military Parade, 2004, p. 158-159).

Despite the fact that the sealed design of this design provides for the operation of the radar in harsh environmental conditions (when exposed to rain, snow, dust and sea fog), the operational reliability of this analogue is reduced due to significant limitations of its work on the effects of air flow (wind load) in connection with a continuous (windproof) waveguide-slot AR fabric.

Given the specifics of modern warfare in the face of intense countermeasures by electronic warfare (EW) and anti-radar missiles (PRR) and the simultaneous use of various types of aircraft, there is a need to expand the arsenal of radar, because weaknesses of the radar in one band can be balanced by the capabilities of the radar in another band.

All well-known domestic portable radars operate in millimeter or centimeter wavelengths, because when designing medium-range radars of the decimeter range, it becomes necessary to take into account the increase in the aperture of the antenna (AR aperture), leading to an increase in the overall dimensions of the structure, i.e. to the deterioration of performance during transportation, deployment and operation in harsh conditions (in wind, in mountainous conditions, etc.).

Due to the lack of a prototype - the closest analogue, namely a portable surveillance medium-range radar operating in the decimeter wavelength range, with a printed-strip flat AR and installed when deployed independently on a removable base, the applicant proposes the claims without division into restrictive and distinctive parts .

The proposed utility model expands the arsenal of portable surveillance radars of medium range and allows you to increase the consumer level of stations with the optimal combination of technical and operational characteristics, which is provided by the proposed block-modular design.

This design is implemented on the basis of spatially spaced and interconnected using cables of a radar module (RL), a module of a rotary support device (OPU), a remote module with electronic equipment that enables and controls operating modes, processes, displays and transmits information, as well as an autonomous power supply unit, wherein the radar module, which includes an antenna array (AR) and a container rigidly connected to it with transceiver equipment, is placed on a horizontal support a platform driven into rotation by an OPU module, consisting of an electric drive located in a single housing combined with a current collector, on the upper rotary part of which the indicated supporting platform is fixed, with the possibility of detachment, and a removable base on which the OPU case is mounted.

The antenna array sheet is formed by the linear module of the radio interrogator and the individual horizontal linear sealed printed multi-element location antenna modules (hereinafter the linear antenna modules) distributed vertically of the AR frame, pushed out from the transport position to the working position along the indicated direction, with fixation of the indicated parts in the extendable part of the frame linear antenna modules using a swivel mechanism.

The proposed design of a portable surveillance radar has a block-modular construction and consists of four independent parts:

Radar module, module with electronic equipment, OPU module and power supply unit.

The radar module includes an AR that can be folded during transportation and a container rigidly connected with it with transceiver equipment located on a supporting platform.

Structurally, the antenna system is a flat equidistant array consisting of five lines of the location channel, one line of the location and compensation channels and one line of the state recognition channel. Between the lines installed reflectors.

The transmit-receive line of the location channel (PPSKL) consists of eight radiating elements (half-wave vibrators). The body of the linear antenna module is made of fiberglass with a thickness of 0.75 mm, on the inner surface of which copper foil is applied. The central conductor is made in the form of a printed circuit board, which is fixed inside the housing using foam plates. Thus, PPSKL is a rigid plate, which allows it to be used as a power element of the AR.

The transmit-receive line of the location and compensation channels is structurally similar to PPSKL.

The receiving and transmitting line of the state recognition channel consists of nine radiating elements.

The radar module transmits and receives a radar signal, as well as primary processing of radar information.

The module with electronic equipment, enables and controls operating modes, processing, displaying information and transmitting data.

An OPU module, the housing of which includes an antenna rotation drive, rotation control and azimuth generation equipment, a low-frequency current collector, and a base for installing and leveling the radar module on the ground and cables.

The OPU module is intended for installation, installation and rotation of the radar module, as well as for ensuring the connection of its equipment with the remote module with electronic equipment.

As a power source can be used batteries or on-board network of vehicles.

This design of a portable surveillance radar can be used autonomously or placed on vehicles (when working with a mount on the machine body, a removable base is not used). In addition, to increase the detection line of low-flying targets, the removable base can be made in the form of a quickly collapsible lifting mast.

In the particular case of the implementation of the claimed design of the radar, the container with the transceiver equipment and the housing of the remote module with electronic equipment are equipped, each, with a combined multi-channel sealed microwave connector, for transmission from the container with the transceiver equipment, via a low-frequency current collector, to a remote module with electronic equipment, signal, using a set of parallel-connected cables.

The combined multi-channel sealed microwave connector consists of two panels - a support and an invoice. The support panel has connecting sockets and rod catchers, and the consignment note has connecting pins and holes for catchers. In addition, through recesses are located on the smaller sides of the patch panel. The support panel is equipped with two threaded connections in the form of a pin with a wing nut. The pins are fixed at one end in the rotary axes located on the edges of the smaller sides of the panel, with the possibility of entering into the through recesses of the patch panel.

The support platform supporting the radar module is mounted on the movable upper part of the rotary current collector case with the help of vertical rod catchers inserted into the holes of the support platform and lateral loop frog-type tension locks.

The AR frame is divided into lower supporting and upper sliding parts, in which, respectively, rigidly fixed and fixed with the ability to move in the vertical direction when folding, the linear antenna modules are made on the basis of three-layer printed vibrator antenna elements enclosed in a fiberglass module housing.

In the lower supporting part of the frame, between the two lower linear antenna modules of the AR, there is a linear module of the radio interrogator.

It is made in the form of separate vertical sealed printed vibrator antenna elements distributed horizontally and mounted on a horizontally located adder sealed printing element.

The sliding part of the AR frame is formed by two side ribs, the lower ends of which are inserted into the telescopic guides of the end solid walls of the supporting part of the AR frame, and the upper ones are attached to the extreme upper linear antenna module. The linear antenna modules of the sliding part of the frame have stops fixed at the bottom. In addition, they are fixed by the ends and center with the help of swivel joints installed on both sides of each folding linear antenna module with the orientation of the longitudinal swivel joints by the plane of rotation of its elements along the web AR and the central transverse swivel plane of the rotation of its elements across the web AR. The axes of the longitudinal articulated joints are attached to horizontal linear reflectors. The latter are fixed with this fastening of the indicated axes of the swivel joints between the linear antenna modules, with the possibility of moving the reflectors simultaneously in the vertical and horizontal directions when they are folded, simultaneously with the folding of the linear antenna modules. In addition, the reflectors have mounting holes for accommodating the axial nodes of the articulated joints.

The result of the proposed design of the AR frame using horizontal linear printed multi-element antenna modules in the form of strips, which additionally also act as frame stiffeners, is that the printed-strip AR fabric turned out to be through, easily folding, but strong enough that relevant both when transporting the radar, and when working in harsh weather conditions (with strong winds). And the fact that the sliding base racks, having a common cross-piece with rods, are removable, makes it possible to place the radar both on the bodies of vehicles and on mast devices.

The proposed block-modular design of a portable surveillance radar is implemented on the basis of spatially spaced and interconnected by cable radar module, which includes a folding AR 1 and a rigidly connected container 2 with transceiver equipment, placed on a horizontal reference platform 3, driven in rotation mounted on the base 4 vertical electric drive 5, combined with the current collector 6, on the upper rotary part 7 of which is fixed with the ability to disconnect this reference platform 3 (see figures 1 and 2), a remote module with electronic equipment and an autonomous power supply unit (the latter are not shown in the figures).

The through web AP 1 is formed by a linear module of the radio interrogator 24 and individual horizontal linear sealed printed multi-element modules 8 distributed vertically of the frame AR 1, expandable from the transport position (see figure 4) to the working position (see figure 2, 3 ) along the indicated direction, with fixing in the extendable part of the frame of the modules 8 using the hinge mechanism.

The sliding racks of the base 4 are attached to the flange 9 of the current collector housing 6 and have adjusting rods 10, ensuring the horizontalness of the OPU module.

The container body 2 with the transceiver equipment and the remote module case with electronic equipment are each equipped with a multi-channel sealed microwave connector 12 (see Fig. 6) with two threaded connections in the form of a pin 13 with a wing nut 14 fixed at one end in the rotary axis 15 on the edge of the support panel 16 (attached to the wall of the container body 2 or the indicated module with electronic equipment) having connecting sockets and rod catchers 17, with the possibility of the pin 13 entering the through hole 18 on the side of the bill second panel 19 with the connecting pins and the holes 20 under the catcher 17, for transmission out of the container 2 with the transceiver apparatus, through a low pass current collector 6, a module with electronic equipment packaged digital signals with a set of parallel connected by cables (not past shown in the figures).

The supporting platform 3, carrying the container 2 with the transceiver equipment and the AP 1, is mounted on the movable upper part 7 of the rotary current collector 6 with the help of vertical rod catchers inserted into the holes of the supporting platform 3 and the side frog type 21 loopback tension locks (see Fig. 2).

The frame AR 1 is divided into lower support 22 and upper retractable 23 parts (see Fig. 2) in which, respectively, rigidly fixed and fixed with the ability to move in the vertical direction when folding linear antenna modules 8 are made on the basis of three-layer printed vibrator antenna elements ( not shown in the figures) enclosed in a fiberglass housing module 8.

In the lower supporting part 22 of the frame AR 1, between the two lower linear antenna modules 8 (see figure 3), there is a linear module 24 of the radio interrogator 11, made in the form of separate vertical sealed printed vibrator antenna elements 25, distributed horizontally and fixed on a horizontally located adder sealed printing element.

The sliding part 23 of the AP 1 frame is formed by two side ribs 26, the lower ends of which are inserted into the telescopic guides 27 of the solid end walls 28 of the supporting part 22 of the AP 1 frame, and the upper ones are attached to the extreme upper linear antenna module 8.

The linear antenna modules 8 of the sliding part 23 of the AP 1 frame are fixed by the ends and the center with the help of swivel joints mounted on both sides of each folding module 8 with the orientation of the longitudinal swivel joints 29 by the plane of rotation of its elements along the web AR 1 and the central transverse swivel 30 by the plane of its rotation elements across the web AR 1. The axis of the longitudinal articulated joints 29 are attached to the horizontal linear reflectors 31.

The latter are fixed with this fastening of the indicated axes of the swivel joints 29, between linear multi-element antenna modules 8, with the possibility of moving the reflectors 31 simultaneously in the vertical and horizontal directions when they are folded, simultaneously with the folding of the linear antenna modules. In addition, the reflectors 31 have mounting holes for accommodating axial nodes of the articulated joints. Linear antenna modules 8 have bottom mounted stops 32, which provide rigidity AR 1 when folded.

A vertical guide is fixed in the lower part of the casing of the electric drive 5, into which the guide pipe 33 is screwed. The pipe is passed through the central hole of the common crosspiece 34, which is able to move along the guide pipe 33 and is pivotally connected to three sliding racks of the base 4 using three rods 35 (see figure 2), which allows you to connect the rack base 4 in a single movable structure (see figure 5).

In addition, the base 4 is equipped with cable braces attached to its upper part in strong winds and secured with stakes (braces and stakes are not shown in the figures).

The proposed design of a portable surveillance radar in the transport position consists of four independent parts, namely: a radar module, including a folding AR 1 and a container 2 with transceiver equipment (see Fig. 4), which is rigidly fixed to the frame of the AR 1, rotary support device, which includes an electric drive 5, a low-frequency current collector 6, a base 4 and connecting cables, a module with electronic equipment that enables and controls operating modes, processing, displaying information data and autonomous power supply unit (see Fig. 5, cables, a module with electronic equipment and a power supply are not shown).

When deploying the radar at the position, first at the OPU module the adjusting rods 10 of the sliding racks of the base 4 are fully extended and fixed, then the racks are moved apart and fixed with a common cross 34. The horizontalness of the flange 9 of the current collector 6 is checked according to the level integrated in the flange. The supporting platform 3, carrying the container 2 with the transceiver equipment and the AP 1, is mounted on the movable upper part 7 of the rotary current collector 6 using vertical rod catchers inserted into the holes of the supporting platform 3 and the side loop tension locks 21 of the frog type. And the folded AR 1 is brought into operation by opening the frame of the AR 1.

Using cables and connectors, including combined multi-channel sealed microwave connectors 12, a low-frequency current collector 6 is used to connect a container 2 with transceiver equipment and an external module with electronic equipment.

The quick deployment of the station is achieved as a result of simple actions, namely, the modules (their components) are sequentially installed on each other and are fastened with quick-detachable joints, without additional fasteners, while ensuring all electrical inter-module connections. Plug connectors are located in easily accessible places.

Convenience during transportation is provided by the proposed designs of the antenna array and the OPU module. Easily foldable antenna array and the base of the OPU module allow you to reduce the size of the packaging.

The implementation of the base removable allows you to install the radar, both on a tripod and on the body of vehicles, and on mast devices.

Thus, thanks to the above design features, it is possible to create a portable surveillance radar of the medium range of the decimeter wavelength range, capable of monitoring airspace at low and very low altitudes, and be mobile and transportable.

During the implementation of the utility model, a prototype of a portable mid-range decimeter range radar has been manufactured, the equipment of which is located in four packaging places. The total mass of the portable radar is ≈120 kg. The dimensions of the radar antenna in the working position are 716.5 × 1260 × 320 mm, and during transportation - 500 × 1260 × 320 mm.

The through array of the antenna array made it possible to increase the mechanical stability of the radar and reduce the rotational moment of the AR and as a result to increase the reliability of the radar in viewing mode in an extended interval of wind loads.
