A radar based detection system having a pulse repetition frequency generator connected to first and second narrow pulse modulators, a transmit channel connected to said first narrow pulse modulator, a receive channel connected to said second narrow pulse modulator, a time delay circuit for delaying output of said second pulse modulator to said receive channel, and a mixer for mixing a portion of one of said transmit pulse channels reflected from an object with said output of said second narrow pulse modulator, characterized in: said transmit channel emits a pulse modulated carrier based transmit signal having a prescribed carrier frequency and said signal having a prescribed duration. |
