Proposal Identi cation No.: ... Hours Proposal Title: Multiple Radar Characterization of the Leonid Meteor Stream and Ionospheric E ects: A Leonids Campaign Proposal for 1998/99. ABSTRACT: We propose to continue the successful systematic observations of the macro/micrometeor component of the Leonid meteor shower and possible ionospheric e ects of the shower using the AO 47/430 MHz radar systems and a user-supplied forward-scatter VHF passive meteor radar. ... Maybe Part of the observing run. ...

... 2.3 Data acquisition Spectra generated by the Multibeam correlator contain the usual structure seen in spectra from other H i instruments: a bandpass spectrum which is the sum of the sky , ground and receiver temperatures multiplied by the product of the filters in the receiver chain; superimposed on this is a noise ... Note also that sources extended much beyond ,40 arcmin can be imaged poorly in HIPASS images because of the bandpass sidelobe effect described in Section 3.3. ...
