Sanders made the pulse doppler active radar seeker. 300w peak power, 100w average. PRF 150-300 kc/s. Dish diameter 12in. Beam width 15 deg. Frequency C band. Conical scan frequency (after acquisition) 200-300 c/s. Max closing speed Mach 8. Max doppler frequency of target 80 kc/s. Range accuracy +-1% of range or 1,000 yards. Guidance range 10nm. Weight of Sanders seeker 90lb + 35lb for Bendix supplied antenna and gimbal.
Aerial is plane polarised with 4 dipole feeds each followed by a ferrite modulator in order to produce an electronic conical scan in track mode. Gain quite low as affected by feeds used by Bendix in home-on-jam mode. Power generated by a Sperry reflex klystron (1w) fed via a ferrite isolator to Sperry 3 cavity klystron power amplifier with gain of 20-25dB.
The receiver used 9 banks of 11 filters.
Two home on jam systems were used. For all prfs there was a clear part of the doppler spectrum between 80 and 110 kc/s where no target or clutter signals should be seen. This could be used to distinguish jamming signals. Also a second receiver (by Bendix) produced midcourse guidance when the host aircraft's AI radar was jammed.
