General Comments ~ ~ ~ ?~ ~ 9 ~ ~ __ .
This report covers the fifth period of contract activity for rmprov~tent of
I~i_' Radar Detection Techniques.
The job has been staffed by two senior engineers working part timei as
required9 and by three full tame engineers, The period has been devoted to basic
design of comF~onerrts to be used in a ftil.l.y i~nplesaented breadboard system.
Activities of the Report Period.
A hish frequency sawtooth generator has been constructed. The Y~i.ghest
obtainable sweep frequency has been l.li me for which rlyback time approached 15~,
Lo.rering the swieep frequency allows for flyback improvement. Because sideband
suppression in the serrodyne technique of frequency translation is a function of
flyback times it is important that this factor be reduced. Continued effort is
being placed on improving the flyback characteristic while maintaining a high
sweep frequency..
The intermediate frequency resulting from the translation process must be
heterodyned to a lower frequency consistent with the frequency separation of
the signal components. An oscillator and rli.~oer has been designed and tested for
a 10 me intermediate frequency. The design frequency may be readily shifted for
any frequency required.
A preliminary desi~ of the active filters has been made and is now being
breadboarded. Provision is being made for samzpling and dumping the filter at
the end of each RF sweep,
The mechanical area scanner is virtually cor~pletet requiring only one
remair-ing part which is in fabrication. Upon its ceaapletian, the scanning
system will be operated in conjunction with the initial systems previously
developed for basic system experimentation.
High wltage sw+sep circuits for the backward 6Tave Oscillator are aperatingb
Refinements in the linearity and sweep range adjustments are currently underway.
Delivery of the Backward Y~Tave Oscillator is expected daily.
Pro~am for the Fhsuing rlonth
All of the work herein outlined wi11 continue during the next periods Saaae
of the work will be concluded and other portions of the system will be begun.
The principal murk to be started i.s the digital circuitry required for sampling
the filter outputs and for providing the appropriate display voltages.
