Description

Plot raw I&Q iqdat format files.

The output is to the X terminal. The program acts as a "virtual" oscilloscope allowing the user to replay I&Q samples taken at the radar.

Examples
iqplot 20080318.wal.iqdat

Plot the I&Q samples from the iqdat file called "20080318.iqdat" on the X terminal.
