1. Typically the main lobe body would have a duration of about 450? 2. This beam is called the main lobe . 3. For monopulse radar, signal processing is identical for the main lobe and antenna beam. 4. The main lobe and side lobes occur for both conditions of transmit, and for receive. 5. The main lobes of the radiation pattern are along the axis of the helix, off both ends. 6. Wider the main lobe of the smoothing spectrum, smoother it becomes at the cost of frequency resolution. 7. In general, the more the sidelobe levels are lowered, the broader the main lobe will become. 8. The sidelobe in the opposite direction from the main lobe is called the " " backlobe " ". 9. The main lobe is again increased in amplitude and the sidelobes correspondingly reduced, giving a significant improvement in performance. 10. The low efficiency significantly reduces gain for a given main lobe beamwidth when compared to other arrays of the same beamwidth.
