Techniques for range finding for an unmanned aerial system are described. As one example, an unmanned aerial system includes at least one motor to provide propulsion, a piezoelectric acoustic actuator having a resonant frequency, a piezoelectric acoustic sensor having the resonant frequency, and a controller to modulate a fixed amplitude and fixed frequency, at the resonant frequency, carrier wave according to a pseudo-random sequence of bits to produce a modulated wave sequence having a respective section of the carrier wave for each bit of the bits of the pseudo-random sequence having a first value, and a respective section of the carrier wave for each bit of the bits of the pseudo-random sequence having a second value, transmit the modulated wave sequence from the piezoelectric acoustic actuator, receive a reflected wave sequence including a reflection of the modulated wave sequence with the piezoelectric acoustic sensor, determine a delay time between the transmit and the receive of the modulated wave sequence based on the reflected wave sequence received by the piezoelectric acoustic sensor and the modulated wave sequence transmitted by the piezoelectric acoustic actuator, and modify power provided to the at least one motor based on the delay time.
