NEMP Simulators
MIL-STD-464 HEMP
Montena designs and manufactures bounded wave simulators capable of conducting HEMP (High-altitude ElectroMagnetic Pulse) / NEMP (Nuclear EMP) survivability demonstration tests on large systems. Fixed simulators for outdoor installation have been developed and marketed for more than 20 years.
The setup mainly consists of a high voltage pulse generator connected to a transmission line ended with distributed resistors. A voltage monitor and various field sensors are used to measure the generator output and the electric and magnetic field strengths in the test area. The resulting signals are transmitted via fibre optic links to a fast oscilloscope and are then displayed/processed in Montena data acquisition software.
Montena proposes as well a range of smaller transportable NEMP simulators for indoor or temporary outdoor installation, for the test of subsystems and equipment according to the MIL-STD-461 RS105.
Two types of simulators are proposed for large EUT's :
Vertically polarized simulator (acc. to MIL-STD 461 RS105)
These large HEMP test systems are taylor designed according to the customers requirements. Examples of realized projects :
| ANTENNA HEIGHT | ANTENNA LENGHT | PULSER VOLTAGE |
| 10 m | 40 m | 800 kV |
| 13 m | 52 m | 900 kV |
| 25 m | 140 m | 2 MV |
Horizontally Polarized Dipole (HPD) simulator
| ANTENNA HEIGHT | ANTENNA WIDTH | PULSER VOLTAGE |
| 10 m | 30 m | 1.6 MV |
| 12 m | 30 m | 1.6 MV |
