Definitions

  • the present invention relates to the general field of sonar protection of coastal areas and the monitoring of ports.
  • It relates more particularly to a means for ensuring, with greater efficiency, the deployment and implementation of sonar systems, installed immersed fixed position, so as to achieve such protection.
  • the underwater environment to be monitored generally corresponds to shallow water, although this depth can reach several tens of meters.
  • the propagation of sound waves is not rectilinear: their path has a curvature that depends in particular on variations in the speed of sound with depth. Since the sea is not a homogeneous medium, but rather a medium that can present different superimposed layers presenting sudden differences in temperature, the sound waves undergo at the level of the interfaces separating the different layers a modification of their trajectory, which results in a curvature this one.
  • the intensity of the deviation of the sound wave paths depends on the velocity of the sound in the propagation medium, itself varying with the depth, so that a sound emitted by a sound source will travel a different path depending on the depth at which this source is located. This variation is also different depending on the climatic conditions and in particular the seasons.
  • the range performance of a sonar is the maximum distance a target can reach so that the sonar that emits an acoustic wave can detect the signal reflected by that target.
  • performance prediction software tools parameterized using bathythermic data, are generally used.
  • the knowledge of the bathythermic readings characteristic of the geographical area makes it possible to determine the temperature gradient in the water column and consequently the sound velocity gradient. This gradient varies mainly according to the geographical position of the measurement and the climatic conditions, in particular the seasons. These readings thus make it possible to determine, for the measurement sites considered, the variation profile, according to the depth, of the propagation velocity of the sound. They also make it possible to establish curves describing, for a given geographical area and as a function of the depth, the paths that can follow the acoustic wave emitted by a source located at a point of the zone. Consequently, if one wishes to set up a sonar monitoring system covering a given area of the seabed, the knowledge of the bathythermic data makes it possible to determine the optimal position of the system.
  • the equipment is, in the vast majority of cases, fixed on the sea floor, on a massive support which serves as ballast.
  • the documents US 5,398,214 and US 3, 418, 624 disclose equipment connected to a massive support for ballast.
  • Such an implementation obviously does not allow to obtain a maximum range in all geographical / climatic cases and for the different types of sonar (frequency, antenna, ).
  • the reverberation especially that from the bottom, is often preponderant and limits the detection range of the sonar.
  • the latter is strongly related to the position of the transmitter in the water column, optimizing the position of the transmitter in the water column is an effective way to improve the sonar detection range.
  • An object of the invention is to propose a solution making it possible to make better use of bathythermal data, when implementing fixed sonar monitoring systems, intended to provide a safety function. monitoring, in order to maximize the scope of the system, taking into account the propagation of sound.
  • An advantageous solution for taking advantage of the bathymetric data, and therefore of the more or less advantageous propagation characteristics that the immersion medium can present at a given depth is to use a sonar placed at a certain distance from the bottom. say placed between two waters at a depth allowing it to offer the best range characteristics.
  • the mast is a telescopic mast whose length is adjustable and comprises remotely controllable adjustment means.
  • the mast comprises means for releasably attaching to the anchoring structure.
  • the float has sufficient buoyancy to float the assembly constituted by the mast, the platform and the sonar when the mast is disengaged from the anchoring structure.
  • the system comprises means for towing the disengaged system from the anchoring structure to a selected site having another anchoring structure.
  • the float is designed to have variable buoyancy.
  • the deployment device has the advantage of making possible the use of a sonar system having no particular compensation of roll and pitch, but also that of a sonar system having these functions.
  • a sonar intended to be placed on the bottom can therefore be used without modifications.
  • Such a system has the advantage of providing long-term monitoring (port or coast protection) which remains effective over time, while bathymetric variations with the seasons have a significant impact on the performance of the system.
  • sonar detection In addition, by making it possible to arrange the sonar heads so as to maximize their range, that is to say between 2 waters and off the coast, the invention also has an interest in terms of overall area coverage. Indeed, in order to cover a given area, the implementation of the invention makes it possible to minimize the number of sonar heads by using an omnidirectional coverage in azimuth (see the example illustrated by FIG. Figures 4 and 5 ).
  • the anchoring structure 11 has the main characteristic of being a massive element capable of staying at the bottom despite possible movements of water bodies. It is also able to keep all the elements of the device immersed. As such, this structure can have a shape and a constitution variable depending on the case. It can thus, as illustrated by the figure 1 take the form of a block of concrete, or any other dense material, placed or anchored on the bottom. It can also for certain particular applications take the form of a metal structure planted at the bottom. In the case of a permanent monitoring system, the support structure is generally installed irremovably.
  • the support mast 12 has for its function to allow the positioning of the platform 13 at a given depth. Its length h is therefore determined accordingly. It is attached to the anchoring structure substantially vertically. Rigid structure, it is designed and realized, in a known manner, to have a resistance adapted to the bending stresses that may be imposed on it, by the movement of water masses in which it is immersed. Its hydrodynamics and masses are determined in order to maintain a vertical position with an acceptable pitch and roll amplitude for the sonar equipment in terms of mechanical stress, as well as in terms of degradation of sonar detection distance performance, degradation due to pitch and roll of the antenna at the top of the mast. It may for example be constituted by a cylindrical pylon made of composite material or metal. In addition, the mast may be designed to limit its own vibrations due to currents, for example by being equipped with a fairing.
  • the platform 13 serves to host the sonar head 16 consisting mainly of the antenna, and, depending on the sonar equipment considered, all or part of the electronics of the sonar transceiver of the system.
  • the sonar head is fixed on the platform, preferably removably, by appropriate means, not described herein.
  • the platform 13 is fixedly mounted at the top of the mast 12.
  • the length h of the support mast 12 is determined from the bathythermic data so that the sonar head 16 placed on the platform 13 is immersed to a depth such that the sonar head has maximum performance in terms of range. detection.
  • the float 14 in turn has the role of limiting as much as possible the movements of the platform, movements mainly consecutive movements of water bodies such as wave movements or currents.
  • the size (volume and weight) and the material constituting the float are determined in a known manner according to the worst weather conditions that can be encountered on the site. Its buoyancy is determined in particular so that the force that tends to bring it up to the surface advantageously opposes any bending movement of the mast while not exerting excessive force on the fastening means which ensures the fixing of the mast 12 to the anchoring structure.
  • the buoyancy of the float 14 is calculated so that the angle ⁇ taken by the mast, under the action of the external constraints imposed by the movement of the water bodies, can not exceed a few degrees, compared to the vertical, this limit being variable according to the type of sonar used (antenna size, frequency, ). In this way, compensation of the movements of the platform is not essential for processing the sonar data.
  • the mast 12 is fixed to the anchoring structure so as to limit the variations of orientation of the sonar head, so that no correction is imperatively required. Nevertheless, it should be noted that since the mast is free in its pitch and roll movements, the use of position sensors can improve the overall performance of the system. It makes it possible to evaluate in real time the impact of the variations of the positioning of the sonar head on its detection performances and possibly to correct this impact.
  • the transmission of the sonar information from the sonar head placed on the platform 13 to the deported processing and management organs, for example on the ground, as well as that of the operating commands sent from these same management organs to the sonar head, is This means, of varied nature, may for example consist of an electrical connection cable or an optical cable. Depending on the applications, these connection means can also be used to supply power to the sonar head 16 as well as to the entire device. A cable then provides two-way data links and power from the shore.
  • the device thus described advantageously makes it possible to position the sonar head at a chosen depth, while ensuring a sufficiently stable position for it so that no particular compensation of the sonar information is necessary because of the movements of the water masses.
  • the device according to the invention is provided with a platform for installing the sonar head.
  • the sonar head can be installed at the top of the mast, directly above the float 14 or if it is designed to include an inner housing, inside this float.
  • the device according to the invention as described above is an advantageous deployment solution compared to that of placing the sonar head directly on the bottom.
  • This solution advantageously makes it possible to position the sonar head at a depth making it possible, to a certain extent, to optimize the reach of the sonar, the compensation of the movements of the mast by the float 14 making it possible moreover to use an identical sonar head, without any particular system of motion compensation.
  • the support mast is constituted by a telescopic tubular structure 21.
  • This structure is set in motion by means for controlling the elongation or contraction.
  • These means not shown in the figure may, in known manner, be mechanical, hydraulic or electrical. They can also be operated remotely from the shore.
  • the connecting cable 15 is designed to transmit the corresponding commands of elongation or retraction. Its configuration is further adapted to take these variations into account.
  • a mast 21 of variable length h is thus available making it possible to position the sonar head 16, fixed at its top, to a depth d that can vary on command, as a function, for example, of climatic or meteorological conditions.
  • the bathythermic conditions being variable over time, particularly according to the seasons, it is advantageously possible with this preferred form of the device according to the invention, to position the sonar head at a depth which allows the moment considered get the maximum reach.
  • a telescopic mast 21 makes it possible to arbitrarily position the sonar head 16 at a given depth. This possibility can for example advantageously find its usefulness when the positioning of the sonar head below or beyond a given depth is for example impossible (or otherwise necessary) because of the presence of temporary natural obstacles (schools of fish, algae, etc.).
  • the telescopic support mast 21 has the characteristic of being fixed to the anchoring structure removably, by fastening means 22, a universal joint and shackles for example, allowing the mast to pass from a locked state in which it is fixed to the anchoring structure 11, in an unlocked state where it is entirely separated from the anchoring structure 11.
  • these locking means 22 are advantageously remote-operable so that the separation of the support mast 21 from the anchoring structure 11 can be achieved without the intervention of divers on the bottom.
  • This configuration is particularly advantageous when the anchoring structure 11 is located at a depth unfavorable to human interventions (typically from 30m), which is quite often the case.
  • this preferred embodiment has great advantages in terms of maintenance and operation.
  • the operations relating to this task can advantageously be simplified by controlling a maximum extension of the telescopic mast 21.
  • the depth d at which the platform is located 13 supporting the sonar head 16 is decreased, which facilitates for example the intervention of divers responsible for disassembly and possibly replacement of the sonar head.
  • a mast 21 that can be extended to an appropriate length it is even conceivable to emerge the platform 13 and make possible a surface intervention.
  • this preferred form of implementation of the device according to the invention makes it possible to facilitate the deployment of the sonar surveillance system of which the device is a part.
  • the fact that the support mast 12 and the elements attached thereto (platform, float and sonar head) can be detached from the anchoring structure 11, allows to consider a variable deployment around the area to be monitored . To do this, it is sufficient, for example, to position anchoring structures 11 by differing selected locations, then to position the sonar head fixed on its support mast vertically to the anchoring structure chosen at a given instant, and finally to immerse the mast and lock it to the anchor structure considered.
  • the float of the device according to the invention may also advantageously consist of a variable buoyancy structure, comprising for example ballasts.
  • a variable buoyancy structure comprising for example ballasts.
  • the device according to the invention offers particularly advantageous possibilities in terms of deployment of monitoring systems.
  • the Figures 4 and 5 illustrate the advantage of using a device according to the invention for producing for example a coastal surveillance sonar system.
  • the figure 4 illustrates how one generally deploys a conventional sonar detection system inside a bay or harbor.
  • the detection system comprises several sonars immersed on the seabed.
  • Each sonar 42 covers an area of the submarine space materialized by an arc 44 more or less complete depending on the surrounding submarine relief.
  • the depth generally grows from the coast towards the center of the bay one is here forced, the sonars being placed on the bottom, to arrange several sonar close to the coast 41, sonars whose number must be sufficient for that together these sonars can cover the entire bay.
  • the control center 43 generally placed on the ground, thus communicates with the various equipment 42 by means of a network of links 45 all the more important as the number of sonar equipment necessary is greater.
  • the figure 5 shows how with the device according to the invention it is advantageously possible to reduce the number of sonar equipment necessary to perform the same monitoring task.
  • the sonar head can be immersed between the surface and the bottom, at a depth which allows both not to be hindered by the relief and to make the best of bathythermic conditions and to obtain a maximum range embodied by the circle 52 in the figure.
  • the optimal configuration illustrated by the figure 5 it is thus possible to cover the area to be monitored with a single sonar equipment 51 placed no longer on the bottom along the coast 41, but at the location of the bay and at the most favorable depth to obtain maximum range.
  • the number of equipment deployed (and hence the maintenance operations) and the quantity of connections 45 needed to link deployed at the Center 43 is obtained.
  • the deployment device according to the invention is described in the context of the implementation with a sonar head. It is obvious that such a context of implementation is neither exhaustive nor limiting.
  • the device according to the invention can be implemented in any other neighboring area where it is necessary or at least advantageous to maintain a submerged equipment at a given depth.
