McDonnell Douglas Radio Services Corp. Attn: G. D. Foote, H362 POB 516 St. Louis, MO_ 63166 EXHIBIT II TO FCC FORM 442 11(a) Program We are building an imaging radar; the type of which we believe will have future application to missile guidance. Our plans include installing the radar equipment in our company aircraft, gather and record radar data in flight, and then signal process the data in our laboratory. Future plans include designing, packaging, and test—flying equipment with a form factor compatible with missile size and shape. Description of Equipment The radar equipment consists of a transmitter, receiver, antenna, and control box. It also contains radar data memory and digital magnetic recording equipment. The transmitter is X—Band, and transmits coherent, pseudo random, bi—hase modulated pulses. The output transmitter stage is a travelling wave tube amplifier which is driven by a frequency synthesizer, the base frequency from which is derived from a stable crystal oscillator. The receiver contains a low noise radio frequency amplifier and inter— mediate frequency stages to match the transmitted waveform. The receiver output is bi—polar video which is digitized and recorded for later processing. The antenna has a one—foot dimension with a 6.9 degree beamwidth. It‘s highest sidelobe is 20 dB below the main beam. It has a 200 MHz bandwidth. The control box contains the switches and controls to control and change the operating mode and parameters of the radar. Theory of Operation The antenna will be positioned to point to the sides of the aircraft velocity vector (sidelooking radar). The radar will be operated as a Synthetic Aperature Radar (SAR). Relatively long pulses are transmitted (through the antenna) and are reflected from the terrain below and to the side of the aircraft. The reflected radar data is received, digitized, and stored for later processing in the lab. In the lab the data will be processed to compress it in range and angle to achieve a high resolution ground map.

In the lab the data will be processed to compress it in range and angle to achieve a high resolution ground map. 11(b) Specific Objectives Objectives sought during this experimental radar program are: — to learn the interaction between equipment and processing complexity on SAR maps resolution and fidelity — to learn what the radar parameters should be for a missile qguidance application 11(c) The program will be used to develop, and extend methods, algorithms, techniques for missile qguidance. The application of imaging radar for missile quidance is a new but growing field, and both U.S. Navy and U.S. Air Force development agencies are presently engaged in research and experimental development programs of a similar nature.

McDonnell Douglas Radijo Services Corp. Attn: G. D. Foote, H362 POB 516 St., Louis, MO 63166 EXHIBIT I11 TO FCC FORM 442 Item 20 The applicant is a wholly owned subsidiary of McDonnell Douglas Corporation {MDC) and proposes to render a non—profit radio communi— cation service to its parent corporation. MDC is engaged in the design, development and manufacture of aircraft, spacecraft, missiles, other aerospace products, and associated supporting equipment for commercial customers and the U.S. Government. The applicant and MDC have entered into an agreement whereby MDC will provide the necessary equipment to support its radio communication requirements. However, the applicant will have full control of the use, operation and maintenance of such equipment in the same manner as if the equipment were owned by the applicant.
