Abstract: A radar system is disclosed which includes a transmitter which produces a long coded radar pulse. The return of the long coded radar pulse is compressed by a long pulse compression filter to produce a short coded pulse and the short coded pulse is compressed by a short pulse compression filter to produce a return pulse for processing by an existing processor designed to process return coded pulses of a particular format. The long pulse transmitter can also transmit a short coded precursor pulse, to improve radar range coverage, along with the long coded pulse by the provision of a switching bypass device which routes the short coded pulse return signal around the long pulse compression filter.

Abstract: A guide pin assembly has a base plate with a first surface from which a guide pin extends. A flexible retaining plate hled by the base plate has a first surface facing and spaced from the first surface of the base plate. A spring member has an elastic portion extending alongside the guide pin from a rotatably retained end portion to a distal end portion. The rotatably retained end portion is in contact with the first surface of the flexible retaining plate and it rotates in response to flexure of the retaining plate.
