A radar system comprising: a reference signal generator configured to produce a transmit reference signal comprising a sequence of waveforms; a waveform generator configured to produce a plurality of transmit signals, each having a different frequency offset from the transmit reference signal; a signal encoder to encode the plurality of transmit signals using a signal conditioning and power amplification to produce and transmit N radio frequency encoded transmit signals over N transmit antennas; at least a first receive antenna for receiving a target return signal reflected from the N radio frequency encoded transmit signals by a target; a downconverter configured to mix the target return signal with the transmit reference signal, thereby producing an intermediate frequency signal; and an analog-to-digital converter connected to convert the intermediate frequency signal to a digital signal; wherein the radar system is characterized in that the signal encoder encodes the plurality of transmit signals in multiple transmit time slots, such that alternating transmit channels are active in a first time slot and are suppressed in a second time slot while a second set of alternating transmit channels are active in the second time slot and are suppressed in the first time slot; and the radar system comprises a radar control processing unit configured to process the digital signal with fast time processing steps to generate a range spectrum comprising N segments which correspond, respectively, to the N radio frequency encoded transmit signals transmitted over the N transmit antennas in the transmit time slots. a reference signal generator configured to produce a transmit reference signal comprising a sequence of waveforms; a waveform generator configured to produce a plurality of transmit signals, each having a different frequency offset from the transmit reference signal; a signal encoder to encode the plurality of transmit signals using a signal conditioning and power amplification to produce and transmit N radio frequency encoded transmit signals over N transmit antennas; at least a first receive antenna for receiving a target return signal reflected from the N radio frequency encoded transmit signals by a target; a downconverter configured to mix the target return signal with the transmit reference signal, thereby producing an intermediate frequency signal; and an analog-to-digital converter connected to convert the intermediate frequency signal to a digital signal; wherein the radar system is characterized in that the signal encoder encodes the plurality of transmit signals in multiple transmit time slots, such that alternating transmit channels are active in a first time slot and are suppressed in a second time slot while a second set of alternating transmit channels are active in the second time slot and are suppressed in the first time slot; and the radar system comprises a radar control processing unit configured to process the digital signal with fast time processing steps to generate a range spectrum comprising N segments which correspond, respectively, to the N radio frequency encoded transmit signals transmitted over the N transmit antennas in the transmit time slots. <EOS>
