MILKAR-4A2 HF Jamming System has been developed for electronic attack operations against HF frequency band communication systems located on different platforms in the field. The system’s aim is to harm or completely block target HF communications and/or cause incorrect data transmission ensuring advantage for friendly troops in tactical field.
The system has a power amplifier subsystem which high power RF output over a wide frequency coverage. Moreover, it uses its own exciter infrastructure with very high exciter tuning/sweep speed and a wide band receiver unit with wide instantaneous bandwidth. Owing to these technologies, the system gains reactive jamming capability. Thus, it can apply effective jamming against the target frequency hopping signals in the field.
The system can apply effective jamming against the targets communicating through ground wave, sky wave and NVIS in HF communication band. For these abilities, the system includes ground wave and sky wave/NVIS jamming antennas. Due to tactical requirements of ground wave antenna, there is a special mechanism on the system for quick set up and tear down capability. With this capability, the system gained fast position change ability in tactical field.
The system has a basic Electronic Support (ES) capability to support electronic attack operations and uses receivers with high sensitivity for detecting and analyzing very weak signals. Moreover, the system has a mission planning tool which helps the operator to plan the operation effectively. By using this tool, the RF propagation analysis can be performed on a real terrain.
Dual power generator, air conditioners and ground wave antenna together with the system shelter are ergonomically integrated on a high-mobile shelterized 10-tone vehicle platform. Since all the system equipments has been carried on single vehicle, the system has high mobility on rough tactical area. Moreover, the system could function independently of the platform. According to the customer’s needs, the system could be deployed on different platforms.
