Description
For ECM, this app is to calculate the J/S ratio for the stand-off jammer (SOJ) situation. In this case, the jammer is at a different location than the target. While the target is in the main beam of the radar antenna, the jammer radiates power into the sidelobes. As an example, for a tracking radar, enter the power in kW antenna gain in dB, and IF bandwidth in MHz. Then enter the aircraft cross sectional area in m^2 and the range in km.Next, for a jammer on board with transmitter power in kW over a bandwidth in MHz and given antenna gain in dB at a distance from the radar in km and a sidelobe in dB level for the radar antenna.
For example, Enter Pt = 100, Gr = 35, Br = 1, A = 4, R = 3, Pj = 1, Bj = 20, Gj = 10, Rj = 10, & SL = 20. Your value for J/S (SOJ) should be -14.0 dB.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
