Morad MANV UHF Military Portable UHF MANV Radio with Frequency Hopping and ECCM Encryption for Ground Operations

The Morad MANV UHF is the infantry portable radio designed for the combatant who operates in contentious electromagnetic environments where adversary forces use broadband or directed jamming equipment (jammers) to disrupt unit tactical communications at the highest operational pressure moments — during a flanking maneuver, urgent extraction, or fire and movement operation where communication between the team leader and support shooters is the factor that differentiates success from failure.

The ECCM (Electronic Counter-CounterMeasures) system implements synchronized pseudo-random frequency hopping among all combat group terminals at 2000 hops per second in the 300-512 MHz band, with a frequency selection algorithm based on a pseudo-random sequence generated by the session cryptographic key — identical in all group terminals — making narrowband jammers ineffective as they cannot predict which frequency will be active in each 0.5ms window, and band-sweep jammers ineffective as they are swept before the signal is on each frequency long enough to be jammed.

Analog/digital mode selection in the same radio allows units with mixed equipment — part of the section with new ECCM radios, part with legacy analog radios — to communicate on the same UHF channel during the equipment transition period, without operationally segregating legacy equipment carriers until complete replenishment of the unit's radio allocation is completed.
