Ray synchronization on angle boundaries

The exact number of samples (M) that is used for each time average is usually set when setting up the operating parameters of RVP10.

The exact value of M that is used for each time average is generally the sample size that is selected by the SOPRM command.

However, when the RVP10 is aligning its processed rays to AZ/EL angle boundaries, the actual number of pulses used may be limited by the number that fit within each ray’s angular limits at the current antenna scan rate. So the antenna scan rate may limit the number of samples averaged. The number of samples will never be greater than the set sample size, even if the antenna is scanning at low angular speed that would allow more samples.

Example: RVP10 is operating at 1 KHz PRF, 20-deg/sec scan rate, 1° ray synchronization, and a sample size of 80. Then, if the LSYNC Dyn bit is set, rays consist of a full 80-pulses ending at each angle and extending back 30-pulses into the previous angle sector. However, when Dyn is clear, there are 50 pulses used for each ray (not 80) and those pulses exactly fill the scanning angle sector.
