FUZES CSA-NGXFM (New Design) CSA-NGXAM (New Design) CONVENTIONAL (Thomson's Desing)
Transmision frecuency band/ Transmitted signal Microwaves / frecuency modulated signal, continuous wave (FMCW) Microwaves / frecuency signal without modulation, continuous wave (CW) UHF / signal without modelation, continuous wave (CW)
Antenna independent of the caliber independent of the caliber The antenna of the fuze is the projectile itself
Multicaliber (5/54, 76/62, 4.5, 3.5, ...) (5/54, 76/62, 4.5, 3.5, ...) NO
Radiation diagram Frontal lobe (It improves the operation in low altitude flights) Frontal lobe (It improves the operation in low altitude flights) Double pole λ/2 (worse operation in low altitude flights)
Doppler signal cicle when it process the last metres Hundreds (It allows more complex and fiable process) Hundreds (It allows more complex and fiable process) Between 4 and 10 (more basic and less fiable process)
Power supply Battery with positive charge between 8V and 10V Battery with positive charge between 8V and 10V Battery with positive and negative voltage (±22V)( It is more comp
Temperature dependence (Between -20ºC and 70ºC) Too low Low Medium - High
High frecuency circuit MMIC Technology (microwaves monolitic integrated circuits) and microstrip, it allows us to obtain a better quality in RF signals and its processed. MMIC Technology (microwaves monolitic integrated circuits) and microstrip, it allows us to obtain a better quality in RF signals and its processed. Too basic,based on a transistor that work as an oslilator and a mixer.
Reliability in th impact detection High High Medium
Sensibility in proximity detection of an aerial target High (Capacity to detect reliably an target of 0.5m2 radar cross section) High (Capacity to detect reliably an target of 0.5m2 radar cross section) Medium (Capacity to detect targets of 1.3m2 radar cross section)
Dependence of the detonation distance regarding the RCS of the target Too low Medium (It increases with the RCS) High (It increases with the RCS)
Sensibility of proximity detection to the sea Detonation arround 10m of altitude (It improves the eficience in fron of maritime targets) Detonation arround 10m of altitude (It improves the eficience in fron of maritime targets) Detontion arround 70 metres of altitude
