The 85 kg Grifo-F P2804 radar is designed to fit into the nose of Northrop F-5, and in comparison to earlier Grifo-L, Grifo-F is larger and has the additional compatibility with active radar guided air-to-air missiles.
[3] Grifo-F shares the same components of slightly larger Grifo-M3 radar, with the exception of its own elliptical antenna, which is unique to the space confinement of F-5.
[9][10][11] Grifo M P2800 series radars are larger and more powerful radars than Grifo-X, and like Grifo-F, Grifo-M also uses multi-processors for fire control, but incorporated additional compatibility with anti-ship missiles (AShM), and also has greater look-down range and better look-down capability by adopting fast Fourier transform (FFT) Doppler-filtering techniques.
As with earlier Grifo series in the family, models in this series also share the same components except the antenna, and due to the different sizes of antenna, the maximum range of each model also various somewhat.
In comparison to earlier series, Grifo-S has the additional compatibility with semi-active radar homing air-to-air missiles,[3] and SAR mode.
