ACIG.org (o Tom Cooper querrás decir) puede decir misas sobre si el Sapfir-23/Sapfir-23ML/Sapfir-23MLA/Sapfir23MLA-2 tiene o no capacidades LD/SD,
Y sobre ACIG-org, es gracioso que en un tema generico dedicado al mig-23 niegan total capacidad LD/SD y en otro sobre su radar afirman que si la tiene.
Segun el manual posteado en acig, los modos son los siguientes:
The mode BSV for high/medium altitudes and all-aspect intercepts, to engage targets flying higher than the Mig-23. (Hc>Hs), pulse width ~4 µsec(search), pulse width ~1 µsec(track), PRF 1Khz, Beam width in search 2,5°. Indicated range scale on SEI is 60km(search), indicated range scale on SEI is 30km(track). The maximal target altitude surplus is 6km. (delta H switch).
The mode BSV-delta H4 uses one half of the PRF compared to the BSV mode. The mode BSV-delta H4 for high/medium altitudes, rear-aspect intercepts, to engage targets flying lower than the Mig-23 on the earth background (LD/SD mode) (Hc<Hs). Pulse width ~4 µsec(search), pulse width ~1 µsec(track), Beam width 2,5°(search). The max. altitude deficit of the target is -4km. (delta H switch).
The mode BSV-delta H1 differs to the BSV-deltaH4 by using the pulse width of 1 µsec (search, track). The mode BSV-delta H1 for high/medium altitudes, rear-aspect intercepts, This mode is used to engage targets flying lower than the Mig-23 on the earth background (LD/SD mode) (Hc<Hs). The signal is further processed, filtered out in the “differential clutter filter” (DKP)
The SMV mode for medium/low altitudes and all-aspect intercepts, to engage targets flying higher than the Mig-23. (Hc>Hs). Indicated range scale on SEI is 30km(search, track). The pulse width of ~1 µsec(search, track)
The MV mode is used to engage targets flying lower than the Mig-23 on the earth background. (LD/SD mode) (Hc<Hs). It`s used only for rear-aspect intercepts, pulse width ~1 µsec(search, track), Beam width in search 1,5°. The MV mode uses the „SDC with external coherence“ technique to compare Doppler shifts between the target and earth background. The antenna scan zone is locked in azimuth and elevation.
The BSV-SC mode is for high/medium altitudes and all-aspect intercepts, to engage targets flying higher than the Mig-23. (Hc>Hs) . The radar mode exploits the same form of doppler processing of the received signal as in the MV mode, but on the background of radio-reflective clouds. The antenna scan zone isn`t locked as in the MV mode.
¿no tiene modo LD/SD para blancos que se acercan?
Y una foto del hud con el radar enganchado, parece un videojuego de los 70 ;)
