Patent ID: 7773028

Claim:
A transceiver for a radar system, the transceiver comprising: waveform generation circuitry configured to generate concatenated pulse waveforms at an IF band, wherein, in a given pulse repetition interval (PRI), the concatenated pulse waveforms comprise a first set of pulses associated with a first carrier frequency and a second set of pulses associated with a second carrier frequency for frequency diversity in one PRI, the first and second sets of pulses having pulses of different lengths and frequencies; transmission circuitry coupled to the waveform generation circuitry and being configured to generate transmission waveforms based on the concatenated pulse waveforms; coupling circuitry coupled to the transmission circuitry and being connectable to an antenna and being configured to send the transmission waveforms to the antenna, receive reflections of the transmission waveforms sensed by the antenna and produce return signals based on the received reflections; and receiving circuitry coupled to the waveform generation circuitry and the coupling circuitry, the receiving circuitry being configured to process the return signals to separate the reflections for each type of pulse in the concatenated pulse waveforms.
