6.7 ModeN Section
This section contains all of the variables used to define an operational mode except for
antenna scan mode and range. Multiple sections (Mode0, Mode1 … ModeN) may be
used. The total number of modes is defined by the NumModes variable in the Master
section.
The parameters contained in the ModeN section include radar products collected,
radiate on/off, pulse width, PRF, and filter options. Many, but not all, parameters flow
directly to the RVP7.
A ModeN section is referenced from the currently executing scan program. From the
user’s point of view, the modes are named (see the Name variable). By convention, the
following relationships are established for the first five modes:
 Mode0- Powerdown.
 Mode1-Standby.
 Mode2-Long Pulse.
 Mode3-Single PRF Doppler.
 Mode4-Dual PRF Doppler.
In the first two modes, radiate is off. Mode2 is characterized by a long pulse width at a
low PRF; therefore, no velocities are acquired. Mode3 and Mode4 use a narrow pulse
width at a higher PRF and the full suite of products (R, V, and W) is acquired.
Note: The total number of mode sections is recorded in the NumModes variable
in the Master section. If you add or remove a section, be sure to update
NumModes.
