Talk:Monopulse radar
From Wikipedia, the free encyclopedia
Following statement is incorrect: "Normally this is achieved by splitting the pulse into parts and polarizing each one separately before sending it to a set of slightly off-axis feed horns." The pulse is transmitted through the sum channel only. Upon reception, echoes are received in both sum and difference channel which correspond to two concurrent spatially-orthogonal beam patterns. Spatial orthogonality is the essence of monopulse, and not frequency, polarization or temporal orthogonality, meaning that the echoes are received at the same time, using the same polarization, and at the same frequency.
Sequential lobing uses temporal orthogonality, conical scan uses spatial and temporal orthogonality and subpulsing uses both frequency and temporal orthogonality. Sequential lobing, conical scan and subpulsing might be easier to implement but yield detection with lower signal to ratio and are thus inferior techniques.
