1 Summary
The CTD-1 magnetic gradient locator(Unexploded Aerial Bomb Detector)is mainly used to detect unexploded aerial bombs that penetrate deeper underground to eliminate hidden dangers and ensure the safety of airports, docks and other transportation hubs. The equipment has functions such as magnetic anomaly field mapping, automatic positioning of aerial missile targets, automatic depth calculation, automatic identification of direction of the missile.
2 Main performances and technical parameters:
（1）Detection depth：For 250 kg aerial bombs that penetrate into the ground and have an angle greater than 30º with the ground, the detection depth is not less than 3m.
（2）Horizontal positioning deviation：For a 250kg aerial bomb, the horizontal positioning deviation is not more than 0.5m.
（3）Using microcomputer technology, it can draw draw the magnetic anomaly change curve and contour map of the measured target on the spot, and automatically display the position, depth and tilt direction of the measure target.
（4）Adaptable working temperature：-10℃～+50℃.
（5）Continuous working period：≥8h.
（6）It has a function of real-time detection and reminder of battery power.
（7）Working weight：≤6kg.
（8）MTBF：≥500h.
（9）Waterproof performance：whole machine can work normally under moderate rainfall condition.
（10）Whole set of equipment is packed in the same box which is moisture-proof and anti-drop.
