Is it possible to increase the field of scope of Sonic Sensor?

If you mean an ultrasonic range module, then not hugely - range is limited by power and sensitivity,
directionality is determined by the transducer acoustics. The later can be modified but you need to
avoid creating any extra reflections that will trigger the receive circuitry.

Your question is not clear. Do you mean "range" or "beam angle/field-of-view" of an ultrasonic distance/proximity sensor?

Maxbotics has a good selection of ultrasonic sensors (expensive compared to the ol' standard HC-SR04), some with a range up to 10 meters and others with field-of-view up to 60 degrees or so.
