High resolution bistatic radar system
专利汇可以提供High resolution bistatic radar system专利检索，专利查询，专利分析的服务。并且A bistatic radar system using separate antennas for transmit and receive and taking advantage of the fact that the net radar resolution depends on the product of the two gain patterns. In one illustrated system of the invention, a low resolution transmitter pattern is combined with an ambiguous high resolution receiver pattern formed of a thinned array of phase controlled radiating elements. The elements are separated by a distance greater than the wavelength of the RF signal. In this thinned array approach, the suppressed receive grating lobes may be placed at alternate nulls of the transmit pattern by spacing the receiver array elements to be approximately one-half the transmitted antenna width. The transmit radar forms a conventional sector scanning antenna pattern that illuminates the forward area and the receiving antenna has elements spaced so they form a multilobe pattern that contains selected spacing of grating lobes. In operation only one of these grating lobes is illuminated by the transmit pattern. The transmit and receive antennas are scanned in synchronism either sequentially or in some jump scan sequence to provide the sector scan display. The system is operable substantially without microwave waveguides in the wings of an aircraft by providing a local oscillator signal that is phase shifted to control the antenna pointing. Other systems in accordance with the invention may also utilize a thinned array for transmitting and a single lobe antenna receiving or may utilize thinned array for both transmitting and receiving.，下面是High resolution bistatic radar system专利的具体信息内容。
