| 摘要 | A system for resolving range ambiguity includes a wave generator a modulator for applying a digital signature to a continuous wave to generate a digitally-signed continuous wave, a transmitter for emitting the digitally-signed continuous wave from the ranging system as interrogating radiation towards an object, a receiver for receiving a portion of the interrogating radiation after reflection from the object, a correlator for correlating the portion of the interrogating radiation against the emitted digitally signed continuous wave according to the digital signature, a processor for determining from correlation in the correlator an elapsed time period between emitting the interrogating radiation and receiving the portion of the interrogating radiation after reflection from the object, wherein the processor calculates a range of the object from the transmitter by employing space-time adaptive processing and to determine a velocity of the object from correlation in the correlator using Doppler detection. | ||||||
