Abstract
A radar object locator having a transmitter radiating carrier energy in at least one band of frequencies and a receiver tuned to a frequency different from that radiated by the transmitter whereby only a frequency band of carrier energy produced by the electrical non-linearity characteristics of particular objects is detected by the receiver.
Claims5
A radar device for remotely detecting compound metal
- objects comprising, oscillator means for generating electromagnetic energy in at least one band of frequencies, antenna means for transmitting said energy in a beam toward said compound metal object, and receiver means tuned to a predetermined functionally related frequency band different from the first mentioned band of frequencies for detecting only that which is produced by the electrical non-linearity characteristics of the object.
