The design and development of ground surveillance radars is very important to the research community. The company FLIR Radars based in Laval is well known in this field. Their radars have to operate very well in the presence of strong winds, thus their influence on their structure will be studied using the subsonic Price-Païdoussis Wind Tunnel that is installed at ETS in the Laboratory in Applied Research in Active Controls, Avionics and AeroServoElasticity LARCASE. In addition, the experience and expertise developed at this laboratory in the fields of numerical and experimental aerodynamics will be used. Thus, four sets of radar equipment designed and manufactured by the company FLIR Radars will be tested in order to validate the loads at high speeds at which the radar needs to operate. The equipment that will be used from FLIR Radars Inc. will be composed mainly of 2 radars that will be installed on a custom (in-house) support called CLU-777 pan/tilt, on another pan/tilt, or they will not be installed on the pan/tilt. The R20SS Radar is larger than the R6 Radar. The 4 sets consist of combinations between the radars R6 and R20SS, and the pan/tilts. The loads expressed in terms of forces and moments estimated numerically on the radar equipment for the maximum speed of 45 meters per second (allowed in the smallest chamber of the wind tunnel) have higher values than the loads that can be now measured in the wind tunnel by the actual 6 DOF forces / torques sensors (balance). Following aerodynamics estimations, a new adaptive chamber test has to be designed and manufactured in order to allow the accurate determination of the loads at the Price-Païdoussis Subsonic Wind Tunnel. The LARCASE team will contribute in the design and manufacturing of the new adaptable test chamber, and the interface that should connect the balance to the model. In addition, aerodynamic numerical validations will be performed in order to validate the experimental values of the loads. A common research work will thus be performed between the FLIR Radars Inc. and the LARCASE teams at ETS.

地面监视雷达的设计和开发对研究界非常重要。 总部位于拉瓦尔的 FLIR Radars 公司在该领域享有盛誉，他们的雷达必须在该领域运行良好。 强风的存在，因此将使用亚音速研究它们对其结构的影响 安装在 ETS 活跃应用研究实验室的 Price-Païdoussis 风洞 控制、航空电子设备和 AeroServoElasticity LARCASE。 此外，该实验室在数值和计算领域积累的经验和专业知识 因此，将使用实验空气动力学设计和制造的四套雷达设备。 FLIR 公司的雷达将进行测试，以验证雷达所需的高速负载 FLIR Radars Inc. 使用的设备将主要由 2 个雷达组成。 安装在名为 CLU-777 云台的定制（内部）支架上或另一个云台上，否则它们将无法安装 安装在云台上的 R20SS 雷达比 R6 雷达更大。 4 套由组合组成。 雷达 R6 和 R20SS 以及平移/倾斜之间。 载荷以力和力矩的形式表示，在雷达设备上进行数值估计 最大速度45米每秒（风洞最小室内允许） 比现在可以通过实际 6 DOF 力/扭矩传感器在风洞中测量的负载的值 （平衡）之后，必须设计并进行新的自适应室测试。 制造的目的是为了准确确定普莱斯-帕伊杜西斯亚音速风中的载荷 LARCASE 团队将参与新的适应性测试的设计和制造。 室，以及将天平连接到模型的接口此外，空气动力学数值。 将进行验证以验证负载的实验值。 因此，工作将在 FLIR Radars Inc. 和 ETS 的 LARCASE 团队之间进行。
