BOX TOP-EQUIPPED MODIFIED FULL HOUSE SYSTEM
IDENTIFIED IN MONGOLIA
NEMEGETE UULA E LINT TRACKING FACILITY, MONGOLIA
25X1
1.' (SWN) SIGNIFICANCE:' AN UNUSUAL MODIFICATION OF THE FULL
HOUSE RADIO INTERCEPT/DIRECTION FINDING SYSTEM WAS RECENTLY
DEPLOYED AT NEMEGETE UULA ELINT TRACKING FACILITY.
2. (SWN) REMARKS: A BOX TOP-EQUIPPED MODIFIED FULL HOUSE RADIO
INTERCEPT DIRECTION FINDING (RI/DF) SYSTEM WAS IDENTIFIED AT
NEMEGETE UULA ELINT TRACKING FACILITY, ON THE 25X1
INTERCEPT SYSTEM CONSISTED OF A BOX TOP RI- DF VAN CABLE
CONNECTED TO SEVEN ADCOCK ANTENNAS (FOUR ADCOCK ANTENNAS FORM
A SQUARE FOUR ARRAY) AND SEVEN MONOPOLES (EIGHT MONOPOLES
FORM A TALL RODS ARRAY). THIS INTERCEPT SYSTEM WAS ORIENTED
IN A FAN-SHAPED CONFIGURATION CONSISTING OF AN 25X1
OUTER ROW OF SEVEN ADCOCK ANTENNAS AND AN INNER ROW OF SEVEN
MONOPOLES. THE CONVENTIONAL FULL HOUSE SYSTEM CONSISTS OF A
BOX TOP/ZIL RECEIVER VAN CABLE CONNECTED TO TWO CIRCULAR
ARRAYS OF TALL RODS AND SQUARE FOUR ANTENNAS. THE
COMBINATION OF THESE ANTENNAS FORM THE SOVIET'S MOST WIDELY
DEPLOYED OMNIDIRECTIONAL INTERCEPT SYSTEM.
(SWN) ANALYSTS COMMENTS -- THIS DISTINCT FAN-SHAPED PATTERN
HAS BEEN OBSERVED ONLY TWICE PREVIOUSLY; FIRST AT TORGAU ARMY
BARRACKS KAVALLERIE 261 AND AT
ODESSA ARMY BARRACKS PROTOPOPOVKA AL-11
ON BOTH OCCASIONS IMAGE INTERPRETABILITY PREVENTED THE
IDENTIFICATION OF ANTENNA TYPES; HOWEVER, THE DISTINCT
FAN-SHAPED PATTERN WAS EVIDENT. ANTENNA ORIENTATION WAS 225
DEGREES AT BOTH FACILITIES. THIS BOX TOP-EQUIPPED MODIFIED
FULL HOUSE SYSTEM IS ESTIMATED TO PROVIDE THE SOVIETS WITH A
UNIDIRECTIONAL AUTOMATED INTERCEPT SYSTEM.
