Abstract
A low-cost, high-resolution radar based detection system has a pulse repetition frequency generator connected to first and second narrow pulse modulators. A transmit channel is connected to the first narrow pulse modulator and emits pulse modulated carrier based transmit signals having a prescribed carrier frequency and a prescribed duration. A receive channel is connected to the second narrow pulse modulator. A time delay circuit delays the output of the second pulse modulator to the receive channel and a mixer mixes a portion of one of the pulse modulated carrier based transmit signals reflected from an object with the output of the second narrow pulse modulator.

A radar based detection system, comprising:
- a pulse repetition frequency generator connected to first and second narrow pulse modulators;
- a transmit channel connected to said first narrow pulse modulator, said transmit channel emitting pulse modulated carrier based transmit signals having a prescribed carrier frequency and said signals having a prescribed duration;
- 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 the pulse modulated carrier based transmit signals reflected from an object with the output of said second narrow pulse modulator.
A radar based detection system, comprising:
- a pulse repetition frequency generator connected to first and second narrow pulse modulators;
- a transmit channel connected to said first narrow pulse modulator, said transmit channel emitting pulse modulated carrier based transmit signals having a prescribed carrier frequency and said signals having a prescribed duration;
- 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 quadrature power splitter connected to a receive antenna, said quadrature power splitter splitting a received pulse reflected from an object into a quadrature channel and an in-phase channel for the detection of the object.
