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.

Android Emulator is a software application that enables you to run Android apps and games on a PC by emulating Android OS. There are many free Android emulators available on the internet. However, emulators consume many system resources to emulate an OS and run apps on it. So it is advised that you check the minimum and required system requirements of an Android emulator before you download and install it on your PC.
Below you will find how to install and run ECM J/S ratio (SOJ) on PC:
If you follow the above steps correctly, you should have the ECM J/S ratio (SOJ) ready to run on your Windows PC or MAC. In addition, you can check the minimum system requirements of the emulator on the official website before installing it. This way, you can avoid any system-related technical issues.
