limit, at which point processing for that ray is terminated. Once this
happens, a new trigger angle is assigned based on which limit was crossed.
The maximum number of pulses that will be present in each ray during
angle syncing is given by the Sample Size field of the SOPRM command.
This is the actual number of pulses that will be used when Dyn=1. When
Dyn=0 the actual number of pulses may be less if a trigger angle is crossed
before the full pulse count can be accumulated
0916-156
Dyn If set, then synchronize the endpoints of each ray but let
their angular width vary by whatever is required to collect
the SOPRM number of pulses. If clear, then the angular
width of each ray is fixed (between successive table
entries) by adjusting the pulse count and reinterpreting the
SOPRM sample size as a maximum value.
Sht Synchronized rays ordinarily will be the full width of
successive table entries (in the static case) or the full
requested pulse count (dynamic case). This bit modifies the
behavior in both modes to allow short rays to be produced,
wherein the pulse count is less than expected due to
encountering some feature in the CPI (usually a trigger
transition) that would normally have resulted in the entire
ray being thrown out. When this bit is set it becomes the
responsibility of the user's code to check the actual pulse
count that went into each ray and manually discard those
that are too short to contain useful data.
Ena Enables antenna synchronization.
El Synchronization is based on TAG1531 (Elevation) inputs,
else TAG015 (Azimuth) is used.
BCD Specifies that TAG angle input is in the form of 4-digit
Binary Coded Decimal; otherwise, a 16-bit binary angle is
assumed.
Ld Indicates that a new table size and array of values follow
the command. If Ld = 0, then LSYNC is a one-word
command only. Otherwise, the following words are used to
load the new table:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
