Number of SPI Bus required for multibeam forming

Question

Q1. For Implementing Multibeam forming using adar1000 do each adar1000 require independent SPI Bus or shared SPI Bus will work ? 
 Q2. How to increase the range to 5km ?

Hi Mihirrr, 
 I don't know what you mean about multi beamforming. Do you just mean using multiple ADAR1000's? On the Phaser, the 2 ADAR1000s are on the same SPI bus, but different chip selects. But you could also address the ADAR1000s differently and have them on the same chip select. 
 For figuring out range, you need to use a range calculator with your target's RCS. I recommend the MATLAB "radardesigner" app for this.)
