Abstract

The invention discloses a vertical monitoring insect radar detection system, which is characterized by comprising an antenna device, a receiving and sending module, a signal processor and a digital collection terminal, wherein the antenna device is used for sending insect detection microwave signals and receiving microwave signals reflected by insects, the receiving and sending module is used for sending the insect detection microwave signals through the antenna device and carrying out amplification processing on the insect microwave signals received by the antenna device, the signal processor is used for receiving signals subjected to the amplification processing by the receiving and sending module and carries out conversion and processing to obtain insect intensity data, the azimuth angle data is obtained through the antenna device, and the data collection terminal is used for analyzing and calculating the obtained insect intensity data and the azimuth angle data to obtain the insect space distribution and time information. The vertical monitoring insect radar detection system and the detection method provided by the invention are used for developing seasonal long-period automatic monitoring of great migratory pests for crops in China, and the real-time monitoring and the early-stage early warning on the great migratory pests can be realized.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a vertical monitoring insect radar detection system and detection method. Background technique [0002] Existing insect radars can detect a variety of important agricultural migratory pests, but traditional scanning insect radars are impractical for long-term and automatic detection of pest population dynamics. Firstly, the scanning insect radar equipment is very complicated, not suitable for long-term automatic operation, and data analysis requires a lot of time and energy; secondly, the scanning insect radar has limited ability to identify types. In theory, when the beam is stationary, if the migrating insect individual If the stay time in the beam is long enough, the system can record the individual's wing-beating frequency. However, due to the overlap between individuals in the same direction, the wing-beating frequency of one individual will be affected by another individual, ...
