A radar system operable to detect objects within multiple ranges using common components is provided. The radar system includes a transmitter antenna, a first and second microwave radiation source, and a receiver. The first and second microwave radiation sources both are transmitted through the transmitter antenna. The echoes are received by the same receiver. The first microwave radiation source is a frequency modulated wave form and the second microwave radiation source is an ultra-wide band wave form. A multiplexer selectively connects one of the first and second microwave radiation sources to the transmitter antenna. |
