Problems solved by technology
However, due to the existence of gravity, the insect body axis is generally not parallel to the fishing line. Therefore, it is difficult to control the angle of the oblique flight, and it is impossible to realize the radar echo data of the insect under different accurate oblique flight angles. Therefore, it is impossible to know the influence of different precise oblique flight angles on the characteristic parameters of insect flight

The present application is a multi-angle observation device for insect flight attitude, which belongs to the field of insect flight experiment research. The center rotates in the circumferential direction; the arc-shaped guide rail is arranged on the rotating table, the plane where the arc-shaped guide rail is located is perpendicular to the rotating table, and the insect is placed at the center of the arc-shaped guide rail; the detection unit is slidably arranged on the arc-shaped guide rail; Two driving units, the second driving unit is drivingly connected to the detection unit; in this application, the insect target is fixed, the position of the detection unit is changed, the detection of insects with different flying attitudes by radar is realized, and the electromagnetic scattering characteristics of insects under different flying attitudes are studied. It is helpful to improve the accuracy of radar measurement of insect flight characteristic parameters, and then accurately judge the law of insect migration, which has important practical significance for the prevention and monitoring of insect pests.
Description
technical field [0001] The invention relates to the field of insect flight experiment research, in particular to a multi-angle observation device for insect flight attitude. Background technique [0002] Insect migration is an important ecological phenomenon in nature and one of the reasons for the formation of insect pests. The migration of pests will cause the outbreak of pests in different places, resulting in the reduction or extinction of food production, threatening the national food security. In order to prevent pest infestation caused by insect migration, effective monitoring of insect migration is required. In the prior art, insect radar is generally used to measure characteristic parameters such as head orientation, body length, body weight, and wing frequency of insects to analyze the types and trajectories of insect targets, which is of great significance for monitoring and preventing insect pests. [0003] Existing insect radars measure characteristic paramete...
