heater 23 a desk 24 and an air conditioning unit 25 are also located in the room 20 these objects include stands to hold objects of interest 17 a rack 21 since the racks 21 may be positioned or oriented at different angles to the detection device of the present invention the orientation of the racks 21 may further complicate its detection the present invention is not limited to the detection of objects of interest that are located behind walls 18 the present invention is applicable to virtually all types of obscurants or visual impediments referring now to fig3 a chart illustrates the various applications 40 in which the present invention can be implemented the chart of fig3 makes it clear that there are environments of increasing difficulty the least difficult environment is the u201c through the walls u201d application and the crowd control application 41 the next more difficult environment is the faa homeland security application 42 the most difficult environment is the foliage penetration application 43 the u201c through the walls u201d application and the crowd control application 41 can be implemented using ground vehicles 44 handheld fixed sites 45 helicopter mounted applications 46 or automatic robotic applications 47 the faa homeland security environment 42 would typically include airport baggage screening 48 and it would include fixed site applications 49 including nuclear power plants large gathering places etc the difficult foliage penetration environment 43 would include large aircraft mounted sources for smart munitions 50 and unmanned combat aviation vehicles u201c ucav u201d 51 referring now to fig4 a diagram illustrates a timing simulation associated with the apparatus and method of the present invention.
