A methodology according to an embodiment includes receiving a signal, generated by a tag associated with an asset in response to a broadcast signal. The broadcast signal comprising a base code sequence, and the received signal comprising the broadcast signal modulated by a tag code sequence and shifted in frequency by a frequency offset. The methodology further includes translating the received signal by the frequency offset to generate a translated received signal, demodulating the translated received signal to remove the tag code sequence modulation to generate a demodulated received signal, cross-correlating the base code sequence with the demodulated received signal to generate a correlation signal, and determining a range to the asset based on a time delay associated with a peak of the correlation signal. The tag may be located based on the range and an estimated direction to the tag."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Asset location using backscatter communication with low probability of intercept and detection","description":"Techniques are provided for asset location using backscatter communication.
