Implementation of a Multi-Beam Radar Coherent-Processing

I am trying to implement a beamforming algorithm for radar application in C langage.
the algorithm process is : Let (x1,x2,..,xnc) be the received signal values from nc sensors, and (y1,y2,..,ynb) the formed beams, numbered nb. A beamformer basic algorithm can be written as a complex matrix multiply, where (y1 y2 ... ynb) T =C (x1 x2 … xnc) T . The C matrix is composed of the beamforming complex coefficients, reflecting phase-shifting and weighting operations.

The questions :
- Where can I find the input signal (x1,x2,..,xnc).
- if someone is already worked on the same topic can explain to me the matrix C.

so this is a phased array radar, or bi static ?

by where do I find the input signals , you have to provide the hardware to get them,
assuming 1024 Tx / Rx pairs to get a reasonable beam, at 1/4 to 1/2 wave length apart.
that the major cost and power of most phased arrays,

thanks for your replying.
But if I don't have the hardware there is an other solution ?
it's a Doppler radar
what about the matrix C that have the coefficients. how can I generate it ?
