1. The radar pulse is generated from the bullet's kinetic energy by a process known as magnetic flux compression. 2. Consider a radar pulse emanating from a radar beacon traveling downwards and interacting with a flat ocean surface. 3. The radar altimeter measures the return power of the radar pulse that's reflected off the land / ocean surface. 4. A beam 1 ^ o wide will illuminate millions of square feet of surface by the time the radar pulse reaches. 5. The bullet emits a radar pulse as it grinds to a halt, offering a safe and efficient way of finding landmines. 6. Unfortunately, it is exceedingly difficult to verify that we have detected an ET radar pulse as opposed to a human-generated transmission. 7. The radar pulse train is used to modulate a radar carrier, the typical spectrum shown on the left will be obtained. 8. The following figure shows an illustration of the vertical cross-section and top-down view of the radar pulse ( adapted from ). 9. In its ultimate incarnation, each radar pulse is sent out on a different frequency and therefore renders single-frequency jamming almost impossible. 10. First, the radar footprint is covering less area so it so the radar pulse emitted by the satellite requires much less power.
