1. A radar system including an antenna, the radar system having short range detection capability, the radar system comprising:

  • a receiver coupled to the antenna for receiving a receive signal associated with a pulse compressed transmission signal;

    a first matched filter configured to accumulate at least a portion of the receive signal for a particular range, the portion of the receive signal corresponding to less than a full pulse width of the pulse compressed transmission signal, wherein the matched filter is implemented using a first pulse decompression algorithm executed by a processor; and

    a full matched filter corresponding to the full pulse width of the pulse compressed transmission signal, wherein the first matched filter is applied to the receive signal at a time less than twice the pulse width after the pulse compressed transmission signal is provided and the full matched filter is applied to the received signal at a time longer than twice the pulse width after the pulse compressed transmission signal is provided.
