Abstract

Abstract A glint simulator is disclosed for receiving and reflecting impinging radar energy to simulate the results of a real target. This allows ready monitoring of a radar response to angle and amplitude scintillation error. A single point source of angle scintillation or glint from the simulator may comprise a microwave antenna, a modulator, a noise modulation source and a modulation phase adjustment. Several simulator point sources may be utilized with a single noise modulator to provide a variable multiple-point target. Simulator antennas receive the radar energy, couple it through respective modulators wherein noise modulation may be introduced to reduce or enhance the energy, and reflect it back to the radar.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 78 words
A glint simulator comprising: a plurality of radar antennas spaced apart for receiving and re-radiating radar energy as controlled point sources; controlling means coupled to each of said radar antennas for modulating said received energy prior to re-radiation thereof, said controlling means are p-i-n diode modulators for modulating said incident radar energy; noise modulation means common to said controlling means; and a sliding short connected to each of said modulators for fine phase shifting of said radar energy.
Claim 2
Dependent Claim 78 words
A glint simulator comprising: a plurality of radar antennas spaced apart for receiving and re-radiating radar energy as controlled point sources; controlling means coupled to each of said radar antennas for modulating said received energy prior to re-radiation thereof, said controlling means are p-i-n diode modulators for modulating said incident radar energy; noise modulation means common to said controlling means; and a sliding short connected to each of said modulators for fine phase shifting of said radar energy.
Claim 3
Dependent Claim 26 words
A glint simulator as set forth in claim 1 wherein said noise modulation means is a transformer having the secondary thereof coupled to said diode modulators.
Claim 4
Dependent Claim 37 words
A glint simulator as set forth in claim 2 wherein said plurality of radar antennas are first and second point source antennas, and said transformer secondary is a single secondary connected in series with said diode modulators.
