Configuring and scheduling of a scan strategy A radar task is the scan configuring procedure, by giving appropriate specifications of PW, PRF, Phase coding, etc as well as signal qualifiers, clutter filters etc. IRIS radar license is a must before configuring a radar task. Normally Analysis system (Main & Standby) has most of the licenses incorporated. As per the orders of <strong>Radar</strong> Lab, DDGM(UI), at present, two common tasks are performed by all IMD radars, viz., IMD-B and IMD-C. IMD-C is a surveillance scan with two elevation angles 0.5degree and 1.0degree with a lower PRF (300Hz) with a scan range of 500 km. The basic moments are restricted to Reflectivity as multiple folding may occur in other moment fields. IMD-B is the volume data scan with ten elevation sweeps, operated at Dual PRF mode of 600/450Hz. The following steps enables one to create an initial scan strategy/Task. STEP 1 : Invoke “iris” though terminal to get the IRIS window 14
