(CNN) Analyst thinks this is why more unidentified objects are being spotted.
CNN national security analyst Juliette Kayyem wants to know the constitution of the “bigger aperture.” I’ll explain the part that any electro-physicist or radar engineer knows.
Decluttering algorithms are essential to radar function. These algorithms are characterized by scales of time, known as time constants. Normally kept fixed, these numbers are now being varied — “swept.” For a balloon, you want a larger number than for an airplane, because in most circumstances, balloons move slower.
The “aperture” has another part. Out of respect for secrecy, I will not discuss what I think it is.
