CUAV 24GHz Miniature UAV Altimeter Radar ISTRA24 The CUAV 24GHz Miniature UAV Altimeter Radar (ISTRA24) has a PCBA size of as little as 45*45mm and a weight of 6.5g, which is very convenient for being integrated into the body of the UAV body or under the arms of the machine. Product Intro (ISTRA24) has a PCBA size of as little as 45*45mm and a weight of 6.5g, which is very convenient for being integrated into the body of the UAV body or under the arms of the machine. An original antenna design. the signal processing algorithm of super-high efficiency and the comprehensive real-time signal processing method of high sensitivity based on the time domain, frequency domain, and phase positions to greatly reduce the physical size of radar modules, making it convenient to integrate the radar model into the body. of UAV and bringing in a brand new probability for the UAV industry. this millimeter-wave-altimeter radar can realize altitude measurement in the range of 0.2 ~ 50m (it is not suggested hovering for a long time under the altitude of 0.5m), which provides a remarkably convenient feature for hovering or flying at a constant distance to the ground by UAV. The constant altitude mode is the most important one among the fly controlling modes of UAVs, while the altimeter radar of high accuracy is the basis for flying steadily under the constant altitude mode. As we all know, in order to make sure the lift force and weight balance, the drone drivers shall pay a lot of attention on slight adjustment operation, while the altitude fixed mode of UAV with the help of altimeter radar may decrease the operation difficulty faced by the drone driver. After entering the alti-tude-fixed mode, it is possible for the drone driver to control the flying directions of the UAV without to balance the lift force, relieving the drone driver greatly and decrease the explosion risks. Furthermore, it is possible to achieve a better. photographing effect when hovering at high altitude with the help of the altimeter radar. What’s more, the altimeter radar is helpful for ensuring steady flying with a constant distance to the ground, increasing the applicability of UAV in specific application scenes including line patrol.

USB connection lead/ radio station for data transmission ISTRA24 Miniature Altimeter Radar connects the open-source flying controller and power input unit (it is not allowed to power up the radar model directly by the flying controller power supply system, please make sure to adopt an independent power supply system). Start the software Mission Planner at the ground station and connect the flying controllers (USB connection lead/ radio station for data transmission) Software running steps are as follows: “configuration/debugging”-“table of all parameters” and set up the following parameters: EK2 ALT SOURCE-1 RNGFND1 TYPE-8 RNGFND1 ORIENT=25 SER1 BAUD=115200(other SER interfaces may also be selected.) SER1 PROTOCOL-9 The operations after configuration are as follows: Click “flying data” and return to the main interface Double click the site circled by the red box in Figure 3 and export the interface “Display This” as shown in Figure 3, cancel other selections with “sonar range” being the only one being chosen, which will display “distance of sonar”, indicating the real altitude of altimeter radar.
