Title: Multi-frequency, multi-target vehicular radar system using digital signal processing
Inventor: ASBURY JIMMIE R
IPC: G01S13/931
Filed: 1993-08-09
Abstract: A vehicular collision avoidance radar system using digital signal processing techniques including a transmit section that generates a two channel transmit frequency. An antenna both transmits the transmit signal and receives a reflected receive signal. A Schottky diode mixer generates a difference signal having a frequency equal to the transmit frequency minus the receive frequency. A signal switch in a front end electronics section time demultiplexes and samples the channel 1 and channel 2 signals. The samples are coupled to a two-channel analog to digital (A/D) converter. A digital electronics section receives the digital information and performs a Fast Fourier Transform (FFT) on each channel of digital data to determine relative speed and range of a target based upon the frequency and the difference in phase of the two channels. The digital electronics section also receives information regarding the status of vehicle operation and/or controls to determine the degree of danger presented by an identified target.

Abstract: The substrate (10) is placed within a housing (12) and heated while setting up within the substrate a temperature gradient so that the substrate has a temperature higher in the portions remote from its exposed surfaces than in the latter. A reaction gas phase precursor of the material to be infiltrated is introduced in the housing, the formation of the material being enhanced in the portions of the substrate having a higher temperature. At the beginning of the infiltration process and at least during the major part of said process, the heating of the substrate is controlled so as to maintain the temperature of its exposed surfaces at a value at the most equal to the minimum temperature of the deposition of material to be infiltrated from the reaction phase, while the remote substrate portions of its exposed surfaces have a temperature higher than the minimum temperature of the material deposition.
