First Claim
Patent Images
1. A short range detection system, the system comprises:
- a transceiver that is configured to;
(a) transmit a step frequency pulse train that comprises multiple radio frequency (RF) pulses that are spaced apart from each other and differ from each other by carrier frequency;
wherein spectrums of the multiple spaced apart pulses completely fill a frequency range in which multiple carrier frequencies of the multiple pulses reside;
(b) receive echoes resulting from a transmission of the step frequency pulse train;
(c) generate detection signals that represent the echoes; and
a signal processor that is configured to process the detection signals to detect at least one attribute of a target.
