1. What can it detect?
It can be used to detect ferromagnetic objects, such as mining areas, pipelines, and unexploded bombs.
2. How deep can it probe?
4-6 times the maximum linear scale of the ferromagnetic target.
 • Sea 30mm projectile (length 17cm) ≥1.2m
 • Sea 37mm projectile (length 38cm) ≥ 1.2m
 • 60mm mortar (33cm in length) ≥ 1.5m
 • 57mm naval shells (52cm in length) ≥ 1.5m
 • 120mm bomb (240cm length) ≥ 5m
3. Detection resolution?
Through the difference algorithm, the system has very low system noise and can distinguish 2nT weak magnetic signal.
4. Ideal flying altitude?
In the case of determining the safety of the system, as close as possible to the ground/water, it is recommended to be 0.5m to 1m above the ground.
5. Can it be detected on water?
Yes, water does not affect sensor operation or weaken magnetic field strength.

Software system
Operating environment: Windows11 home Edition 22H2, display resolution 1920×1080, memory above 8G, Intel(R) Core(TM) i5-8400@2.8GHz 2.81GHz.
Usage method
a) After the sky end of the aeromagnetic detection system is powered on, it can work normally only after the optical pump is preheated for 20 to 30 seconds
b) Connect the ground end data transmission module to the computer or handheld computer through the USB port, open the corresponding serial port, and the data will be automatically parsed and stored in the format of text documents to the local file
c) By adjusting the window length of the drawing, the amount of data in the data display window can be changed in real time, but the size of the window itself will not be changed
d) By clicking the "New File" button, you can change the stored file path at the same time of data collection (currently using the default path, you can execute the root directory of the file)

Functional characteristics
1. Apply "outlier elimination algorithm" to filter the dead zone outliers in real-time data collection
2. Based on the obtained geographic and magnetic data, the clock Alignment algorithm is applied for data fusion
3. Apply "spatial interpolation algorithm" to realize spatio-temporal mapping imaging of latitude and longitude and magnetic field data
4. After imaging, select fine areas for separate imaging again, and focus on magnetic field imaging of key areas
5. Based on the "particle swarm optimization algorithm", retrieve the depth and position information of the target
6. Identify and judge suspected targets based on "deep learning"
