2. Antenna Fig A 1 Radar A 1 1 Antenna How Radar will perform is largely determined by its antenna or scanner Increas ing the size of the antenna improves long range performance and target discrimi nation or the ability to distinguish two separate targets at a distance The critical factors are the antenna s beam width and side lobe level Typically a Radar an tenna will radiate a tightly focused beam from the front of the array The longer the antenna array is the narrower the beam width will be Additionally it will also emit smaller amounts of energy to each side The lower the side lobe level the less the effect of a false echo A 1 2 Side Lobe The beam in which the strongest radio signal is radiated from the antenna is called the main lobe Those beams that are radiated in other directions are referred to as the side lobes The side lobe level refers to the difference in level signal strength between the largest side lobe and the main lobe User Manual 49 Side lobe Antenna Fig A 1 2 Antenna Pattern A 2 CHARACTERISTICS OF RADAR WAVE Radio waves travel out from the antenna while bending slightly along the earth s surface The amount they bend depends on atmospheric conditions The sight distance of a Radar generally is about 6 longer than the optical sight distance and is calculated using this equation Radar sight distance NM 2 22 Vantenna height m Vtarget height
