1. A radar system for investigating surface as well as subsurface areas of interest, comprising:
- an RF transceiver and antenna in communication with said RF transceiver, both of which are provided on an elevated platform, said RF transceiver producing a plurality of chirp signals directed to at least one area of interest, said plurality of chirp signals covering an entire frequency band, wherein each individual chirp signal covers only a finite portion of the entire frequency band, said RF transceiver receiving reflected signals from at least one area of interest, said antenna transmitting said plurality of chirp signals and receiving said reflected signals in a sequential manner;
a processing device in communication with said RF transceiver for processing said reflected signals; and
a storage device in communication with said processing device for storing the signals processed by said processing device.

Abstract
A method and system for examining subsurface targets utilizing an elevated or airborne platform. A broad spectrum of frequencies is transmitted from the platform and is directed at the various subsurface targets. A plurality of chirp signals would be utilized to transmit the entire frequency range. These signals are reflected from the various subsurface targets and are received by the platform. The received chirp signals are combined in a manner to allow the visualization of the subsurface target.
