Radar field-generating antenna CrossOver

IP65wide-bandmulti-band

Overview
The CrossOver series by ImpulseRadar is a family of professional Ground Penetrating Radar (GPR) systems designed for subsurface inspection and geo-surveys. Available in three models (CO4080, CO1760, CO730), the series covers six frequencies across the 70–800 MHz range. Each system integrates a true dual-channel CrossOver antenna with built-in control electronics and an internal GPS module. Real-Time Sampling (RTS) technology enhances depth penetration and bandwidth beyond conventional GPR designs. Systems support wireless control via an Android tablet and are powered by a 12V Li-Ion battery (typical autonomy up to 9 hours, depending on mode). Units can be deployed on dedicated push carts, pulled with a harness, carried by hand or transported by vehicle at survey speeds.
