Tracking
•
Dynamic Band Width Enable/Disable
–
This setting allows the software to automatically adjust the AZ
and EL noise bandwidths for best tracking of the target. When enabled, the tracking algorithm uses the
Settings
–
Mission
–
Track Dynamic Bandwidth MIN and MAX parameters. It is recommended to
keep this setting enabled. Unchecking (disabling) this function, stops the automatic adjusting of the
Dynamic (tracking) bandwidth, relies upon the manually entered settings (below the Dynamic BW
Enable box) and allows the user to manually adjust the AZ and EL Noise bandwidths (default settings
of 1.0 Hz). Manually adjusting these bandwidths can cause the Antenna Tracking System to track
poorly, or cause large oscillations of the antenna during target tracking. In most cases, the automatic
adjustment of the Dynamic Tracking BW provides the best target tracking capability of the tracking
system. In limited cases where automatic BW adjustments do not provide good target tracking, the user
can disable the Dynamic BW and manually enter the AZ and EL Noise Bandwidths to improve system
tracking.
•
Noise Bandwidth Azimuth
–
The default is 1.0 Hz. The AZ noise bandwidth is manually entered in
this field when the Dynamic BW Enable is not active (turned off).
•
Noise Bandwidth Elevation
–
The default is 1.0 Hz. The EL noise bandwidth is manually entered in
this field when the Dynamic BW Enable is not active (turned off).
Note:
The Noise Bandwidth parameter essentially adjusts the AZ and EL tracking gain, which can
cause poor tracking if set too high or low. This parameter is factory adjusted and set for best tracking
(when Dynamic BW Enable is On) for the system feed and antenna size.
•
Receiver
•
Input Type
–
Sets receiver input to HyperTrack
™
(digital) or Analog; the default is analog
•
Input Source
–
When in digital mode (HyperTrack
™
selected), any source or combination of sources
can be mapped to any channel. For example, if the drop down menu of Virtual HT Combiner 1+2 is
selected, then Channel 1 is mapped to be a virtual combined channel of Channel 1 + Channel 2.
Analog is the default setting, where each channel is 1 to 1.
•
Strobe Delay
–
Accounts for filtering and other delays through the receiver; factory adjusted and set (in
this example 65 usec)
•
Sample Discard
–
Typically, used with the Quasonix SCM feed; sets the percentage of tracking feed
modulation signal (AM), which is discarded due to signal changes at higher modulation rates; factory
adjusted and set (in this example 25%)
•
Am Source Impedance
–
Selects and sets the AM source impedance from the attached receiver;
typically set to 50 Ohms, but may vary by receiver type
•
AM Offset
–
Used for receiver compensation when installing a receiver which is NOT a Quasonix
RDMS receiver
•
AGC Scale
–
User adjusted for AGC meter scaling; settings available are 5 dB/div, 10 dB/div, and 20
dB/div (in Figure 102, 20.0 dB/div)
•
AGC Zero
–
User adjustable AGC zero level; typically matched to receiver AGC zeroing, calibration
(in this example 0.0 dBm)
•
AGC Source Impedance -- Selects the AGC source impedance of the attached receiver, typically 50
Ohms, but may vary by receiver type
•
AGC Offset
–
For receiver compensation when installing another receiver which is NOT a Quasonix
RDMS receiver
