Abstract
A frequency hopping continuous wave (FHCW) radar system which utilizes a one-coincidence sequence to create a form of FH multiplexing to allow discerning returning signals from interference. An EHC code generator sends codes to an FH waveform generator coupled to a transmitter. A receiver outputs a received signal to a correlator which correlates received signal with a delayed transmitted signal, and sends results for digital signal processing to determine target range and velocity. Use of the one-coincidence sequence provides for the interference level to be well managed and below the radar return signal; assuring that the returning radar signals can be discerned from interference.
