Each single system that the radar is made out of will correspond to pixels and graphics on the output, and computer systems running the math of the system will allow people to easily get an idea of what the plane looks like and where it is.
Both the laser and satellite would likely have to be custom. Due to the large distance between the earth and a geostationary satellite, the beam waist radius would have to be incredibly large. While they are makeable, they are not available for commercial sale or use, and would have to be custom ordered.
The satellite would likely have to be specially designed to hold and operate the radar. As a result, the ground base would also have to be specially built for the radar, such that it has the capacity to reflect and receive the signals. However, many other parts of the radar can be created using standard parts. Beam splitters, mirrors, and detectors can all be ordered using standard, current models. Detectors may not be available for commercial sale at the precision necessary, but they are currently being made.
Consider what will be needed in the design phase, the creation phase and the testing phase.
We will need equipment such as 5 millimeter and 2 inch 50/50 beamsplitters, a single photon pulse laser with a wavelength of 1550 nm and a beam waist radius of 31.4 mm, as well as highly polished sheet mirrors. Additionally, we will need superconducting nanowire single-photon detectors as they are quintessential to our radar's design, testing, and outcomes.

After going over the decision matrix, feedback and coming up with a design we still need to answer these questions:
Relative size of satellites and ground system
Number of laser systems
Margin of error in computer model
Then after answering these questions we need to do the following:
Figure out the math for our project and the right angles needed
Code a computer simulation to show how our project works
Building a physical model, while it wouldn't work it would help show how our model visually works
Build a CAD model to show the physical parts of our system
Simulation
Adding Ground Station
Precision enhancements
Improvements to visuals & usability
General
Further physical testing
Hammer out satellite specifications
Higher detail digital model
