Could a Pearl-class cruiser carry modern radar?

Could a Pearl-class cruiser carry modern radar and serve as a presence ship today?

It was probably large enough for some modern radar, on a scale comparable with a River-class patrol ship.

The question carries the reuse argument into a modern counterfactual. A Pearl-sized hull was probably large enough to carry some form of modern radar, based on its scale compared with a River-class patrol ship. The answer is limited to the feasibility of fitting a sensor rather than a complete modernization design. It identifies available hull and deck space as one reason an old platform can retain adaptation options.
