This is what the Radar Operator/pilot may see in their cockpit while flying along in their plane. The bearing line (red arrow) represents the bearing of the radar transmitter moving from left to right (Sector) from the nose of their plane.

The EW operator,  situated somewhere within the beam of the radar pulse (Lets say the Red X), is able to intercept the Weather Avoidance Radar. The strong point of the signal is when the radar pulse hits/paints his EW antenna. 

Based on the measurement ability of the EW system, the EW operator may be able to determine  from the intercept details what type of radar it is.  If the operator has other tools like IFF and their own radar, the operator may be able to correlate the emission to a platform.

The weather avoidance radar pictured above is mounted in the nose of the airplane as indicated by the yellow arrow.  This type of radar is primarily used to provide advance warning on inclimate weather along the aircraft’s intended route. The radar is able to sweep in a sectored area , <180° , with some tilt ability.

The intercept station above depicts the IP-480 Analysis screen of the  AN/WLR-1C.  Along with the audio

provides an example of what an EW operator may see on their scope when listening to the intercept.
