Thus now the tasks are configured and scheduled. Any time a scheduled task can be<br />
stopped by right clicking over command area and selecting Stop. Actual scan<br />
strategies followed at DWR PALAM can be seen in D.2.4.5 of APPENDIX D.<br />
1.9.1. Checking whether new scan strategy is working<br />
The newly scheduled scan strategy can be checked by a simple command “productx product<br />
name”. This command when applied to a raw/basic/derived product, it will show all details of<br />
that product, e.g., the server from which it is derived, from which task it is generated, what is<br />
THE PRF,FREQ., and wavelength, at that time, melting level height, power, band width, and<br />
noise of the transmitter, Rx bandwidth, Scan type, Scan speed, Height of radar a.m.s.l: F.,<br />
Processing Mode FFT, Thresholds of different parameters, no. of sweeps, each having 360 rays<br />
and no. of bins and Angle list.<br />
Example for new scan strategy :<br />
