Appeal No. 2000-0519
Application 08/800,627
signal is matched-filter processed during an integration
time of N periods and is subjected to Doppler and distance
processing.
Claim 1 is reproduced below.
1. A method of discrete [sic, discreet] radar
detection comprising the steps of:
at transmission, producing an encoded waveform,
from a multicarrier signal, repeated on at least N
periods, N being greater than or equal to 1, wherein
said multicarrier signal is an orthogonal frequency
divisional multiplexed (OFDM) signal with orthogonal
carriers; and
at reception, carrying out a matched filtering
operation, a Doppler processing, and a distance
processing of received signals.
The Examiner relies on the following prior art:
