A discussion of the diffraction limit of the X-wave pulse is also provided. This confirms the fact that time windowing the infinite energy X-wave excitation is a viable scheme for constructing finite apertures. The decay behavior of the radiated pulse is similar to that of an X-wave launched from a finite-time aperture. Furthermore, the decay pattern of the radiated X-wave pulse is derived for a source consisting of an array of concentric annular sections. It is shown that the finite-time X-wave propagates to much farther distances without significant decay. The decay rate of the peak of the X wave is compared to that of a quasi-monochromatic signal. Huygens’ construction is used to calculate the amplitude of the radiated wave field away from the finite-time source. The analysis is carried out by using a Gaussian time window to time limit the infinite X-wave initial excitation. Also, the possibility of using a finite-time excitation of a dynamic aperture to generate a finite-energy approximation to an X-wave pulse is explored. 30 seconds after ending my first call I had a dog come in.bottom line, for $600 it should be 5 stars.The feasibility of exciting a localized X-wave pulse from a finite aperture is addressed. The other weekend I took my Shockwave out for one of its first sets to try out my new sounds and after 10 min of calling with nothing coming in and not hearing any echo off some trees 300 yds away, I switched to my MFK distress call. But even with my Shockwave turned all the way up to 40, it was only equal to 65 on the Alpha Dog, and even tho Ive never turned it up that loud the Alpha Dog goes up to 100. I transferred sounds from my Primos Alpha Dog to my shockwave and those sounds are WAY louder. The other star is that the quality is great as well.the biggest fault Foxpro (I have the Shockwave) has is that it doesnt matter how great the sound recording (quality) is if it cant get the sound out there, what good is it? The sounds are recorded too quiet. I gave it 2 stars for a couple reasons: The sounds actually sound great, so that is one star. I will not own another FoxPro call unless they decide to do something different. They also don't stand behind their products. Customer service was horrible in my opinion, the people are nice to talk to but nothing is taken care of in a timely matter. I tried downloading the new sounds and it did the same thing it did the first time. They shipped it ground and after 4 days I finally received it and it didn't have the new sounds on it. They also said they would ship it 2nd day and the new sounds would be downloaded on the call. Finally, after many days and many emails, they decided to charge me only $25. I had the call less than a year but didn't have a receipt so they said it wasn't covered under warranty. I sent it to Foxpro and they wanted to charge me $80+ to fix the SD card, said the battery box was corroded, and the LCD was not working in the remote. It wouldn't work and somehow trashed out the SD card. Bought the sounds and tried to download them to my Spitfire caller.
