This is the adaptive sounding sampling task, which is used by the

normal_scan_nodata RCP to count the amount of scatter received.



The task receives fit data from echo_data and uses the sampling routines in

the Radops2000 library to calculate the number of beam/range points which

have more than a specified value of a selected parameter. The minimum

distance at which scatter should be counted can also be specified.

no_data is used by sending a QNX message requesting either that the scatter

count be returned or that the count be reset.



The task is compiled by typing 'make' in the no_data directory. This compiles

and links two versions of the file, the normal version and a debugging version

which displays useful information on the console.



Usage information is available from the QNX 'use' command.
